Château de Monbadon, Medieval castle in Puisseguin, France.

Château de Monbadon is a medieval castle perched on a promontory above the Barbanne valley, featuring thick defensive walls and a distinctive square tower. The structure displays the typical construction methods of fortifications from that period with its characteristic shape and solid stonework.

The castle was founded in 1330 when King Edward III of England granted permission to fortify this strategic position. The fortress remained in private ownership over the centuries and has been maintained by the same family since the early 1600s.

The castle's name comes from the Monbadon family, who held the seigneurie in the 14th century. The square tower, with its flat brick courses between stone quoins, is a local building trait found in several Gironde fortresses. The tower's lower chamber was used as a grain store, and its loopholes are still visible from the outside.

The site sits on elevated ground above the valley, offering good views of the surrounding landscape. Visitors should expect a rural, still-inhabited building that can be viewed from the exterior.

The square tower rises from a promontory above the Barbanne valley, and its walls are built of locally quarried limestone. Edward III's 1330 licence to fortify is the earliest documented reference to the site, and the same family has held it since the early 1600s.
