The coastal towers that watch over the Italian coasts represent a heritage of great historical and architectural value. These artifacts, combining the form of architecture and the forms of the territory, highlight stretches of coast with great landscape value and constitute a huge resource for the territories to which they belong. A stretch of coastline of great interest is Calabria Ultra where the “TO_KNOW” project—financed with resources from the National Recovery and Resilience Plan—aims to revolutionize the way the coastal heritage of this territory is managed and enjoyed. Through an integrated technological, historical, and cultural approach, the project aims to transform the coastal towers, often abandoned and in ruins, into focal points of knowledge and representation of the territory, in line with the new analysis methodologies linked to the archaeology of architecture. The keystone in the choice of case studies is the Romano Carratelli Code, a documentary treasure that provides detailed descriptions of the toponymy of the places and the geometries that were to govern the arrangement of these coastal architectures in the territory. The management of the coastal turreted heritage is therefore guaranteed first of all by the cataloging and analysis of the state of the art of the architectural asset, compared to the ninety-nine watercolors in the archive, the theoretical basis for valorization and fruition. The final objective of the project is to make this rich heritage of knowledge accessible through web apps that can allow users to discover cultural and historical routes.
