The main threats to the integrity of the property are high numbers of international tourists that represent a very important economic resource for the regional economy. The area of the small lake formed by earthquakes and thermal sources around the ancient civil agora, where thousands of tourists can swim between the ancient columns and marble architectural decorations, is particularly threatened. This has led to biological pollution and constant erosion of the ancient Roman marble elements, and the relevant authorities are planning to set up a monitoring system to assist in managing this problem.
