‘Montagne castle dates back no further than the 14th century. At that time it had three towers, one of which was polygonal and inside the keep, and the others circular, flanking an oblong building at the east and west corners of its south face. This oldest part, to the south of the current castle, is also a little higher, and the keep, with its machecoulis and domed gatehouse, dominates it, as does the entire manor house’.
Raymond Guinodie, Histoire de Libourne et des autres villes et Bourgs et son Arrondissement, Tome 3, 1876.
After being restored by Viollet-le-Duc in the 19th century, the Château des Tours gradually fell into ruin. It is privately owned.
