Presentation
A perfect square, this construction is firmly established at the top of the rocky outcrop. It measures 8.10m square, 12m high, with walls 2m thick. It comprises a vaulted storehouse, a first floor and a platform terrace. The tower was somewhat modified in 1865 following the installation of a clock: the vaulted store was almost entirely destroyed and a door was opened on the east façade. The building was restored between 1991 and 1993.
