This thesis examines the preservation challenges heritage cities face because of climate change, with Venice as a case study and references to Rhodes Town, Edinburgh Castle, and Old San Juan. Dominant literature and scholarship on Venice compete with one another, restricting opportunities for interdisciplinary collaboration and dialogue in producing a more efficient preservation approach to the city. Through a study of the brief history of Venice, the materials, and past and present approaches to preservation, this research signifies the need to understand and preserve building materials. Following an analysis of the scholarship on Venice, this paper reveals the role of building materials in discourse on the city, as materials can bridge the gap among competing literature. Therefore, this thesis makes a key contribution to the understanding of urban history and preserving historic cities. In exploring preservation techniques and considering how the discourse can more effectively address the challenges of sea level rise of historic cities, this thesis argues the history of materials is key to a cohesive preservation approach for Venice's built heritage. The building materials are at the center of the preservation issue, and by serving as the core of dialogue and interdisciplinary collaboration, a more efficient approach to preserving the city's local and global heritage will occur. This thesis shows historic building materials can become central to Venice's preservation approach with increased vocal concerns about the building materials from restorers/conservators, non-governing residents, art historians, scientists, and global onlookers to Venice's local government, the Italian government, and international preservation bodies.

Literature on Venice compete with one another, restricting opportunities for conversation on producing an efficient preservation approach to the city. Through a study of the brief history of Venice, the materials, and past and present approaches to preservation, this research signifies the need to understand and preserve the building materials. The role of building materials in discussions and debates on the city is necessary as materials can bridge the gap among competing literature. With building materials at the center of the preservation issue and the core of conversation among different disciplines, a more efficient approach to preserving the city's local and global heritage will occur.
