Discovered during the restoration works in 1974 along the ancient perimeter walls of the church of the Immaculate Conception, they are located under the current floor level and lie in a desolate state and require immediate maintenance. When they were discovered, one could admire some writings and the figure of a saint (perhaps San Vito). Only a few meters of paintings that extended along the perimeter of the current naves were saved, but there were probably others. Unfortunately, the whole thing was covered by a layer of concrete.
