The preservation and management of historic maritime heritage have become critical, due to the interference of industrial, commercial
and logistic activities, which represent a high risk factor. The paper is going to describe and discuss methodologies and results achieved
in the study of historic ports of Apulia, proposing an additional level of research that leads, on the one hand, to the definition of a
methodology for risk analysis and, on the other hand, to the identification of guidelines and innovative instruments for monitoring,
preservation and enhancement of built heritage.
