The Château des Tours was built in the 14th century. At that time it had three towers: one had a polygonal interior and was the dungeon, and the others were circular flanking an oblong building on the east and west corners of its south face; then, at the same corners on the north face, there are sentry boxes with Corbels. The oldest part is in the south of the present castle and is also a little higher.
North of the original castle there was a courtyard formed by the castle and crenellated walls outside with wide and deep ditches below. These ditches remain but the walls were replaced in the 16th century by rectangular buildings. At the east and west corners of the north facade there are two round towers, less high than the others, but topped like them with machicolations. There is a door between these two towers above which are the Arms of Calvimont carved on a large stone: they have lain since 1793 a few steps in front of the door.
The castle was restored by Viollet-le-Duc in the 19th century.References:
Redipuglia is the largest Italian Military Sacrarium. It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.
