En los primeros años de la II Guerra Mundial se ejecutó un sistema de defensas militares sobre el litoral de Cerdeña constituido básicamente por búnkeres y baterías de hormigón, muchos de los cuales siguen en pie como "testarde rovine" que se resisten al paso del tiempo. Esta red dispuso sus elementos sobre el territorio atendiendo a criterios tácticos de vigilancia, control y capacidad de respuesta ante un ataque siguiendo un plan previo que guarda relación con el sistema de torres centinelas de la edad Moderna y que es simultáneo a la construcción de otros "muros" por toda Europa. Sus restos, numerosos y repetidos como objetos industriales, son portadores de valores negativos y de discordia desde su propia concepción: máquinas para matar, en defensa propia, por lo que resulta difícil encajar este patrimonio arquitectónico en el concepto de identidad compartida. El caso de Cerdeña es representativo de este legado ya que los elementos superan el millar esparcidos por toda la isla, por lo que se profundiza en el estudio de la zona de Bosa en la costa occidental, acotada por dos torres históricas, inventariando y clasificando los tipos de las piezas que restan (aportando un alzamiento fotogramétrico), para plantear opciones de protección y conservación de esta herencia de los conflictos armados del siglo XX. Las propuestas de re-uso distinguen el contexto cultural y geográfico – urbano o rural – en el que se insertan las ruinas y tratan de integrar este patrimonio incómodo en el paisaje histórico costero como un estrato más de la acción de los hombres a lo largo del tiempo. ; Nei primi anni della Seconda Guerra Mondiale sulla costa della Sardegna venne realizzato un sistema di difesa costituito essenzialmente da bunker e batterie in calcestruzzo armato, molti dei quali ancora conservatisi come "obstinadas ruinas" che resistono al passare del tempo. I nodi di questa rete, simultanea alla costruzione di altri "muri" in tutta Europa, sono distribuiti sul territorio in base a criteri tattici di vigilanza, controllo e capacità di risposta ad un attacco nemico, secondo un modello del tutto affine al sistema di torri "sentinella" dell'età moderna. Le strutture superstiti di tale rete, numerose e ripetute come se fossero oggetti industriali, sono in genere portatori di valori negativi per la loro originaria natura: erano macchine per uccidere, per autodifesa, e per tale connotazione risulta difficile integrare questo patrimonio architettonico nel concetto di identità condivisa. Quello della Sardegna – con più di mille manufatti sparsi in tutto il territorio – rappresenta un caso significativo. In questa occasione si prende in considerazione una parte della costa occidentale dell'Isola, in particolare nell'area di Bosa, delimitata da due torri storiche, attraverso la realizzazione di un inventario – supportato dal rilievo fotogrammetrico – e la classificazione per tipi delle strutture conservate, con l'obiettivo di avanzare proposte finalizzate alla tutela e alla conservazione di questo patrimonio, che rappresenta una delle eredità delle guerre del XX secolo. Le proposte suggerite per il loro riutilizzo tengono inevitabilmente in considerazione del contesto culturale e geografico – urbano o rurale – in cui queste strutture sono inserite, con soluzioni che consentano di integrarle come testimonianza di una fase importante della Storia. ; In the first years of the Second World War along the coast of Sardinia, a system of military defenses was built consisting essentially of bunkers and concrete batteries, many of which are still standing, as "testarde rovine" that resist the passage of time. This network has been structured on the territory according to tactical criteria of vigilance, control and ability to respond against an attack and based on a project that has a link with the system of towers-sentinels of the Modern age and is simultaneous to the construction of other "walls" throughout Europe. His remains, numerous and repeated as industrial objects, are bearers of negative values and discord from his own conception: machines to kill, for self-defense, so it is difficult to relate this architectural heritage with the concept of shared identity. Sardinia is representative of this legacy because more than a thousand scattered elements have been built throughout the island; the proposed analysis deepens the theme in the study area of Bosa, on the west coast, bounded by two historical towers, proceeding with the inventory and classification of the pieces that remain (with the contribute of photogrammetric survey and 3d models) in order to propose options for the protection and conservation of this legacy of the twentieth century armed conflicts. The proposals for reuse distinguish the cultural and geographical context –both urban and rural– in which the ruins are inserted and try to integrate this singular heritage into the coastal historical landscape as a further layer of the actions of the men along the time.

The fortification "a la moderna" of Pisa in the Modern Age was not made, as in other Tuscan cities, with the construction of a new bastioned front, but strengthening the pre-existing medieval walls. The construction of the new front was developed between the 16th and 17th century in two different phases. In the first phase, starting from the mid-16th century, a few of small bastions were built in some strategic points of the medieval circuit. Only in the first half of the 17th century, the defense system was completed by the military engineer Gabriello Ughi, with demilunes and outworks in earth. The new defense system, demolished in the late 18th century, is described only in a series of historical maps and archival documents. This paper therefore aims at proposing the first results of a study on the 17th century fortification project, starting from a graphical analysis of the historical maps, in order to understand the design choices in the light of the progress of defense techniques at that time and of the constraints determined by the pre-existing structures and the orographic context

The text proposes a comparison between the fortifications (bunkers and batteries) erected during the decade 1936-45 along the Mediterranean coasts of Spain and Italy and the network of defense architecture built in modern times. The needs to considering both architectural and landscape Heritage gives opportunity for new debate concerning the matter of conservation. In particular because those latest elements are the oldest armored ruins of modern 20th-century architecture. This group of bunkers and coastal and anti-aircraft batteries is called Muro Mediterráneo for its formal and functional affinity with the Atlantic Wall built by the German army during World War II (circa 1942) along the coast from France to Norway.The comparison with the "network of sentinel", erected by the Christian kingdoms in the Modern Age (XVI-XVIII sec.) along the Mediterranean coast for his defense, showed similar design criteria, location, functionality and materiality, however, while the 'sentinels' are protected by laws, the contemporary casemates are not. Among these, the differences are (without considering the age difference) as the towers have strong volumes emerging from the profile of the territory while bunkers and batteries (with similar geometric models) are mimetically integrated with the topography of the places where they are inserted. The elements of the Mediterráneo Wall form a new anthropic landscape which can be considered a monument for its allegory of tomb and memorial at the same time.

El presente artículo plantea el paralelismo, histórico y patrimonial, entre las torres vigías del Mediterráneo de los siglos XV a XVIII y los búnkeres y baterías de hormigón armado construidos durante las guerras mundiales del siglo XX en relación a la construcción del paisaje territorial que percibimos de la costa aplicado al caso del litoral valenciano en España y el sardo en Italia (Alicante y Cerdeña). Por un lado, se equiparan este tipo de construcciones históricas y modernas, por otro, se comprueban los similares planteamientos tácticos, territoriales, arquitectónicos, funcionales, técnicos, constructivos y de presencia en el paisaje. Se reflexiona en torno a la percepción visual y sensitiva actual de este paisaje cultural para su defensa y protección en un ejercicio que traspasa las actuales fronteras. ; Universiadad de Alicante (España) y Università degli Studi di Cagliari (Italia)

The present article illustrates an interdisciplinary methodology for the protection of fortified old towns and the management of their possible future transformation. Specifically, the study has developed a process of investigation to support the identification, assessment and conservation of material evidences related to the urban walls inside old towns. The disciplinary fields involved in the research are mainly history, drawing and restoration, supported by diagnostics on materials and structures, urban planning and sustainable design. The testing area is the walled city of Cagliari, a typical Mediterranean fortified settlement, highly stratified with a wide chronology of structures and interesting military constructive techniques. The research develops a working structure for the reasoned collection of contributions belonging from different disciplinary fields. The complex set of information implements a detailed knowledge plan conceived as a vulnerable risk map. Landscape and visual perceptions of the surrounding environment are also considered. The complex mosaic of interdisciplinary knowledge has been the basis for the proposal of effective policies for protection in order to forecast, guide and control possible transformative scenarios. Contemporarily, the management plan includes some strategic actions for the fruition and enhancement of the walled perimeter, such as new touristic paths or entertainment and sporting areas. Criteria and methodology resulting from this article seem to be easily applicable to other contexts, especially in the Mediterranean settlements.

La necesidad de considerar el patrimonio arquitectónico y paisajístico da la oportunidad para un nuevo debate sobre el tema de la conservación. En particular porque esos últimos elementos son las ruinas acorazadas más antiguas de la arquitectura moderna del siglo XX. Este grupo de bunkers y baterías costeras y antiaéreas lo denominamos 'Muro Mediterráneo' por sus características formales y funcionales de afinidad con el Muro Atlántico (Atlantik Wall) construido por el ejército alemán durante la Segunda Guerra Mundial (alrededor de 1942) a lo largo de la costa de Francia hasta Noruega. La comparación con la "red de centinelas", erigida por los reinos cristianos reinos en la Edad Moderna (siglos XVI-XVIII) a lo largo de la costa mediterránea para su defensa, muestra criterios de diseño similares de ubicación, funcionalidad y materialidad; sin embargo, mientras que los "centinelas" son protegidos por las leyes, las casamatas contemporáneas no lo son. Entre estos, las diferencias son (sin considerar la diferencia de edad) que las torres tienen grandes volúmenes que emergen del perfil del territorio mientras que los búnkeres y baterías (con modelos geométricos similares) se integran miméticamente con la topografía de los lugares donde se insertan. Los elementos del Muro Mediterráneo forman un nuevo paisaje antrópico que puede considerarse un monumento por su alegoría de tumba y monumento al mismo tiempo como señaló Paul Virilio. ; Polo Museale della Sardegna; Università degli Studi di Cagliari; University of Edimburg; Istituto Italiano dei Castelli

The essay shows some results of a research aimed at building a digital database of Sardinian military architectures of Second World War. Following an activity of cataloguing entrusted to integrated digital survey methods already applied in other case studies of the region, this contribute analyses the built heritage placed in territory of Bosa, a centre located in the west coast of the island, in which 33 bunkers have been founded, most of them represented in the IGM military historical maps. These "modern sentinels", positioned along the coastline, the main roads and the railway leading to the actual urban context, are designed in reinforced concrete, also integrated with local stone, with a frequently use of square and circle shape often combined or modified and adapted to achieve a complete mimesis in the landscape that hosts them. The survey, applied at architecture and landscape scale, has produced a complete collection of data functional to realize an interoperable digital database, a necessary tool for a deepened knowledge and enhancement of a lost WWII heritage.

La cinta muraria di Cagliari costituisce un importante esempio di architettura militare, tutelata per il suo valore storico-ambientale e paesaggistico, della quale conserva la forma impostata dagli Spagnoli nella metà del Cinquecento e le opere volute dai Piemontesi nel corso del Settecento. In particolare la sequenza di opere "alla moderna", che dal bastione Santa Croce si susseguono lungo l'asse nord-sud in direzione del bastione Balice, e gli ampliamenti situati nel settore nord e nel settore orientale costituiscono il risultato di una serie di trasformazioni che hanno ridisegnato e ampliato la linea difensiva sostenendo logiche insediative, religiose e militari. L'attuale conformazione di sito pluristratificato custodisce le testimonianze dei diversi passaggi che hanno " ridisegnato e scolpito" le forme dei luoghi e creato un paesaggio che connota fortemente il quartiere Castello e la città stessa. Una tutela consapevole di un patrimonio storico caratterizzato da valori e criticità richiede una conoscenza approfondita delle trasformazioni avvenute e un'analisi delle dinamiche in atto, affidata ad indagini multidisciplinari. Lo studio dei diversi aspetti utili a garantire una consapevole gestione del patrimonio storico è tuttavia nelle mani degli specialisti, padroni di un linguaggio -a volte di difficile comprensione per i profani- che necessita di mezzi di rappresentazione appropriati al fine di favorire una più ampia diffusione e una maggiore consapevolezza dei valori. Una rappresentazione che fino all'Ottocento è stata principalmente finalizzata alla descrizione del progetto architettonico oltre che alla documentazione dei luoghi, come nei taccuini dei viaggiatori. Tuttavia, la complessità della stratificazione storica della città contemporanea richiede l'utilizzo di un linguaggio strettamente tecnico e di un'illustrazione scientifica che a volte sacrifica gli aspetti legati alla divulgazione. Il passaggio dal modello puramente tecnico a un modello di facile lettura diviene uno degli obiettivi di una più ampia ricerca -presentare e illustrare le trasformazioni urbane- che trova nella piazzaforte di Cagliari un'opportunità per esplorare le diverse modalità di analisi grafica e di linguaggi affidati a strumenti tradizionali e digitali, anche integrati. ; The city walls of Cagliari are an important example of military architecture protected for its historical-environmental and landscape value. The actual conformation of a multi-layered site preserves the signs of the different changes that have "redefined and sculpted" the shapes of the places creating a landscape that strongly characterize the Castello district and the city itself. The sequence of bastions located in the north and in the western sector of Castello, in particular, is the result of a series of urban transformations that have redesigned and expanded the defensive line by supporting settlement, religious and military reasons. A conscious protection of a landscape characterized by values and criticalities requires an in-depth knowledge of the transformations happened and an analysis of the dynamics in progress, entrusted to multidisciplinary investigations. However, the knowledge of the many aspects useful to guarantee a mindful management of the historical heritage is in the hands of specialists, masters of a language -sometimes difficult to understand for the layman- that needs appropriate means of representation to support a wider dissemination aimed to a bigger awareness of values. A representation that until the nineteenth century was mainly aimed to describe the architectural project as well as the documentation of the places in travelers' notebooks. However, the complexity of the historical stratification of the contemporary city requires the use of a strictly technical language and a scientific illustration that sometimes sacrifices the aspects related to disclosure. The transition from the pure technical model to a model easy to read is one of the objectives of a broader research -representing and illustrating urban transformations- which finds in the stronghold of Cagliari an opportunity to explore the different ways of graphic analysis and languages entrusted to traditional and IT tools, including integrated ones.

Le fortificazioni della Sardegna a partire dal 1720 sono interessate da una serie di progetti mirati al potenziamento delle difese. In quest'epoca, su iniziativa del governo sabaudo, si realizzano nell'isola numerosi interventi lungo i litorali -con la costruzione e ammodernamento del sistema di torri litoranee- e nelle piazzeforti di Cagliari e Alghero con l'ampliamento dei circuiti esistenti. Le nuove soluzioni prevedono l'impiego di forme e soluzioni tecniche quali controguardie, bassifianchi, tenaglioni e opere a corno. A Cagliari il fronte occidentale è uno dei settori oggetto di nuove opere ed il bastione cinquecentesco di Santa Croce riceve nella prima metà del Settecento una serie di modifiche e ampliamenti. La soluzione formale progettata nella metà del XVI secolo dagli ingegneri militari al servizio della Corona di Spagna in epoca sabauda vedrà difatti la realizzazione, ad opera dell'ingegnere piemontese Felice De Vincenti, della Scuderia di Santa Croce per la caserma dei Dragoni (1723-1728) trasformata nel 1736 nella caserma di fanteria "Carlo Emanuele III", struttura in funzione sino al 1838. Per la sua difesa, nel novembre 1732, si demoliva il roccione sottostante il Bastione e con il materiale di risulta fu costruita nel 1733 la Controguardia di Santa Croce, un'opera a V con le facce parallele a quelle del bastione. Le modifiche attuate ridisegnano il funzionamento dell'opera militare; alcuni passaggi in uso a partire dal Cinquecento perdono la loro funzione, sostituiti da nuovi percorsi voltati e sistemi di risalita individuabili nella cartografia settecentesca custodita presso l'Archivio di Stato di Torino e ancora presenti nell'attuale assetto del complesso monumentale. La loro individuazione e la comprensione della funzione da essi svolta quali "componenti della macchina da guerra" guida la realizzazione di un modello digitale che, costruito a partire dall'analisi delle fonti e dal rilievo delle strutture esistenti, permette di rileggere, rappresentare e comunicare la complessità del sistema costruttivo settecentesco.

The paper illustrates the decisions behind the creation of a digital database of military architectures built in Sardinia during the Second World War. This stylistic repertoire is characterized by an interesting historical-cultural and landscape value and composed by more than 1.500 artifacts positioned along the coast of the island to protect the major urban centers and the areas of strategic interest. A correct recovery and enhancement of these historical heritage necessarily needs a previous activity of knowledge and cataloging entrusted to integrated survey methods where digital and traditional tools works together to define an updatable and interoperable graphical model. The database become the place where studying these "stubborn ruins" also comparing geometry, materials and construction technique adopted in other countries. The need for mimesis has required an adaptation of the typological solutions designed by the Italian Military Genius and indicated in the archive documents offering interesting case studies. The first results of this path of knowledge is a complete catalog of small bunkers placed in the east sector of the territory of Cagliari, within the Natural Regional Park of Molentargius-Saline.

The integrated method is been applied in the meet point between the curtain of Santa Chiara and the curtain of de Cardona, in a limited area of the ancient walls of Cagliari (Sardinia, Italy). The sector consists of a bastion called "curtain of Santa Chiara" designed in 1575 and realized in the period 1575-1578 by the military engineer Giorgio Paleari and the "curtain of de Cardona", a military work commissioned by the Viceroy in the 1930s of the same century and interested by modification until the seventeenth century. The archive documents offer a lot of informations on the presence of gunboats and vaulted passages designed and built in this area during this period. This source –accompanied by an architectural survey of the existing military work and the knowledge of the construction techniques used at the time and indicated in the military treaties– may direct a subsequent investigation with geophysical methods. To this aim, a first graphic representation of the study area in the sixteenth century is proposed.

The 43rd UID conference, held in Genova, takes up the theme of 'Dialogues' as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with 'others', which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, "dialogue" as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title 'translated' into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences.
