Cistern

Monsanto

Inside the enclosure, next to a cliff, there is a well that is commonly and mistakenly referred to as a cistern. It has two semi-circular arches, but no roof, which collapsed. Recently, it was partially cleared of rubble in a clumsy cleaning operation. The real cisterns are located at the top of the citadel, where traces of a small tank can still be seen, what remains of its bottom, and another one that has since disappeared. on the opposite side at the foot of the Gothic wall. In the late Medieval era, the main water supply appears to have been this well, and for that reason a shield was built for it, a wall projecting from the citadel wall, with a forward tower around the water point, which also integrated a second access door to the castle core, but these structures did not come down us today.
