A sanctuary with three fana (Gallo-Roman temples), a small bath building, an amphitheatre, several necropolis and remains of buildings where discovered in 1763 and excavated in 1956 near Bern.
It has an ellipsis shape arena, whose axis are 28 x 26 metres, two walls which could be an entry at one end, and a niche at the other end. Its blenches were probably wooden made. Long regarded as an amphitheatre (it would one of the smallest in the Roman empire), the building could be also a Gallo-Roman theatre (according a recent hypothesis), and the walls opposite to the niche would be the basis of a wooden scenic building. The proximity of the amphitheatre with the sanctuary is significant and it could used for various public shows as well as religious ceremonies.
At the north of the amphitheatre, in the forrest, a small public bath-house is visible under a modern roof. The building, discovered in 1847 and entirely excavated between 1937 and 1938, was 20 metres long and 12 metres large. The bath-house has a cloakroom (apodyterium), a cold bath (frigidarium) with a pool, a warm room (tepidarium) and a hot bath (caldarium). The underfloor heating system is quite well preserved.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
