The circus tower has been subjected to several changes across the centuries, but it still conserves a basis and a nucleus from the Roman times. The tower was initially part of the fourth century Roman Circus. During horse races, the horses would leave from this point and then went around the interior of the circus seven times before arriving at the winning post. In the eighth century, on the place of the Roman Circus a monastery was built. The tower, preserved to a height of 14 meters, was integrated into the monastery as church bell tower.
