The Château de La Salle certainly originated from the stronghold of Ozignac, which gave its name to the current hamlet of Louzignac, located near the castle.
Located in the middle of a vast plain, the Château de La Salle is a classic building, sober, rigorous and of great coherence, which seems to have been erected in one go. Built on a north-east-south-west axis, it is accompanied, to the south-east, by a vast lateral courtyard lined with outbuildings, to which formerly corresponded, to the north-west, a tall forest which sheltered it from the winds. dominant. The set was preceded by a long straight avenue lined with trees whose layout is barely discernible today, but which is revealed by the first cadastral plan of Gémozac. It led to the forecourt which was further punctuated by two identical pavilions covered with tiles. Only the corner one remains. That of the north corner, although protected in 1990 as historical monuments, disappeared after being damaged by a fire.
The castle itself is built in the axis of the forecourt, on a rectangular embankment surrounded on all sides by ditches cut in the rock, which allowed the extraction of part of the building materials. It is accessible by crossing an axial bridge with two arches. The ditches are protected by square section balusters, except in the northern part, where they have disappeared. Composed of a ground floor and a first floor, the residence of the lords of La Salle includes, on the arrival side, a main building at the back of the courtyard, framed by two symmetrical side wings. Of the same height, these three bodies of buildings are covered with a roof topped with Roman tiles, except on the two small sections placed on the side of the forecourt, where the flat tiles were used. To the south-west, on the side of the old parterres, the castle develops a more generously lit facade. Before certain openings were blocked, it had eleven bays, regularly organized from the axial bay which is marked by an elegant bridge-perron with three arches spanning the moat. Each of the two corners is marked by a fore body with three bays arranged in the extension of the side wings of the facade overlooking the forecourt (see the aerial view).
The south-east side wing contains the old kitchen which is still covered with a semi-circular vault.
