A small castle with lots of details and intrigue. It is of course a private property, but you only have to see it from the road to realize that.

The best thing to do after visiting the top of this motte is to see it from here in relief. It is strangely a perfect cone or rounded shape. It is very impressive.

This rather unusual topographic feature must have been the seat of a kind of defensive building. Today, only two crosses remain and the stunning views that can be found at the top.

The Moncassin village is built on a ridge overlooking the Petite-Baïse. Le Castéra, located on a limestone promontory dominating the valley, is one of the most remarkable castle mounds in Gascony.
