[EN] The restoration - following decades of abandon-ment and vandalism - of Palladio’s Villa Sarace-no is now twenty years old. This article presents a personal reflection by the architect in charge of the restoration on the occasion of a commemo-rative seminar held at the villa. The text, trans-formed into a declaration of principles, compi-les interesting ideas and concepts applicable to restoration, including sprezzatura (as opposed to affectation), tempered restoration to its original state or imperfect restoration. With the passing of the years, the restoration of this building ap-pears to have functioned correctly confirming the original decisions and intuitions of the...
[EN] The surface conservation is the architectural pla-ce where the technical horizon and the critical horizon come together. In the case of cultural he-ritage, the instruments of the project (such as the cleaning and the reintegration procedures) not only follow the laws of applied chemistry but also embrace the horizon of the interpretation and the historical and critical evaluation of the signs of time. Through an aesthetic and technical reading of known cases, chosen trans-chronologically, the surface acts as the place where the relations-hip with time and history takes on the consisten-cy of matter becoming the place of the project
[EN] There has been a revival of interest in and routine use of hot mixed air lime mortars in the UK and Ireland over the last two years, though many involved have been using hot mixed mortars for ten years or more. The ‘Hot Mixed Mortars Revival’ has been the collective effort of Irish, Scots and English masons and conservation professionals and has re-energized the lime movement across the British Isles. This paper seeks to provide a narrative for this, as well as to summarise the essential benefits of hot mixed lime mortars for use in the compatible repair and...
[EN] The structural consolidation work on Villa Poiana, a unique work by Palladio designed and built using solely vaults without resorting to lineal structures, has given rise to an extraordinary interpretation of the evolution of the structural decay of the buil-ding over time. It is also a model intervention gi-ven its ability to adapt to this progressive history of lesions and deformation, designing added rein-forcement based on the historic structure and its progressive reinforcements. The analysis of the damage that can be caused by interventions with reinforced concrete on historic structures is equa-lly interesting due, among other reasons, to the...

[EN] The use and abuse of historic towns and cities in Puerto Rico is the subject of constant de-bate due to inadequate interventions and the uncontrolled growth of traditional urban fabric and the metropolis in general. The deficiency of General Plans, the limited effect of fragmentary interventions, the unjustified homogenization of historic zones, the governmental misunders-tanding of fundamental heritage issues, and the quality of life necessary for our cities to conti-nue to serve humans, are issues discussed in the text. Specific examples demonstrate des-tructive processes that continue in use despite public outcry

[EN] The second oldest church in the New World is located in San Juan, Puerto Rico and has rea-ched a critical state of deterioration requiring both structural and conservation interven-tions to assure its permanence. In 2004 it was placed on the World Monuments Fund List of the 100 Most Endangered Sites in the World. A series of condition surveys by architects, structural engineers, archaeologists, and con-servators carried out extensive documenta-tions and analyses of the temple between the years 2000 and 2012. This article synthesizes the studies, conservation measures and re-commendations done during this time period.
[EN] Taking into account the gap between time as a philosophical topic and the different –even practi-cal– factors stirring a restoration project, the re-search this paper derives from analyses the role the perception of time plays within the modern concept of monument, as a documentary evidence of multiplicity, whose appreciation can be an ever changing experience. Assuming time as a peculiar dimension of an artifact makes both the concepts of entirety and decay change and deliberately brings a time frame into the project of restoration, enhancing the idea of intervention as a never end-ing interpretation.

[EN] This text presents a detailed account of the history, construction and conservation of this building and its structure prior to intervention, and serves as an interesting example of the construction techniques used by local Baroque and Neoclassical master builders. It then presents the practical programme for enterprise, innovation and knowledge in the local town council as well as the intervention criteria used to guide the restoration. The analysis of the historical construction, mainly rammed earth walls and tile vaults, the repair of wooden eaves using wood prostheses, and the intervention on existing tile vaults which resort to local building...
[EN] This text presents an in-depth study of the Italian postwar atmosphere that eventually gave birth to the Venice Charter. It investigates the debate on Italian historic centres, many of which were heav-ily bombed during the Second World War. At the time, debate on their future focused on whether to protect them or open up to urban planning. The article reviews the role of the main advocates of the international charter on monument protec-tion, Piero Gazzola and Roberto Pane, together with other Italian and international figures such as Raymond Lemaire, in their prolonged struggle to ensure the recognition of anonymous...
[EN] This article describes the lengthy restoration of a major palace in the city of Venice. This included not only the delicate repair of the structure and inte-rior appearance of the palace, which had previously been greatly neglected, protecting it principally from the rising waters of Venice, but also the provi-sion of a complex museumization programme. The compromise achieved between material conserva-tion and updating to contemporary standards and museumization are an excellent example of the benefit of adopting clear criteria for the careful res-toration of monumental buildings, even ones which are severely damaged and technically highly chal-lenging. The restoration process...

[EN] This article analyses the evolution of the concept of cultural heritage in recent years, examining the oc-casions on which it was considered to review the articles of the 1964 Venice Charter as a result of changes within the discipline. This work also exam-ines critical observations of the concept and useful-ness of these charters and the proposals arisen to modify the charter, especially in connection with dif-ferent anniversaries and various international con-ventions. Finally, it highlights the importance of a group of lecturers from the Politecnico di Milano pre-senting an alternative to the classic concept of res-toration based on permanent care...
[EN] This article illustrates the methodology, criteria
and design options considered in the intervention
to visually and materially restore the original
flooring of the basilica of Santo Stefano Rotondo.
The author examines the choices and different
effects in a carefully considered intervention with
an extremely detailed design and execution. The
second part of the text includes a similar reflection
on the challenge of planning lighting and designing
appropriate lamps for each situation according
on the desired atmosphere for the space and the
distinctive connotations of the types and shapes
of lamps proposed. Although the age and the
religious involved great complexity, the character
of the basilica intervention dealt sensitively with
[EN] The author expounds on the subject of the sometimes diffuse limits between replica and restoration by referring to parallel examples from the world of art, technology, cinema, furni-ture, applied arts, etc., subsequently returning to the world of architecture and evaluating the concept of authenticity and the ethical limits of replicas from first principles. A particularly re-vealing approach in this issue is the introduction of the concepts of scale and the final aim of the intervention leading to a clear resolution of any doubts arising. The text is of great interest given its detailed analysis of actions usually linked to...

[EN] Nondestructive evaluation techniques are extensively used in the field of architectural heritage conservation in the United States. This paper outlines the most used techniques, classifying them in visual assessment techniques, and techniques based on wave propagation. Depending on the type of wave, the latter group is subdivided in electromagnetic and acoustic techniques. The final section includes a two nondestructive techniques facilitators: unmanned aerial vehicles and Tablet PC Annotation System
