At the foot of the castle of Lanquais, rises an imposing barn, known as the tithe barn. It has a sloping roof and a frame with three naves whose pillars, made of an enormous oak, have resisted time.

If the barn was really a tithe barn, it is because it was connected with a religious authority. But to this day, it is impossible to find a satisfactory answer, even if links exist with the Cadouin Abbey and the bishops of Périgueux, who owned the first Castle of Lanquais.
In turn the Barn would have been used as a hospital, a Protestant temple, a room for popular festivities, a wine storehouse, a cowshed, and finally, a sheep-fold.

The Barn, in very bad condition, was scheduled for demolition, when the association Friends of Lanquais (Amis de Lanquais) bought it in 1975, and assured a first restoration.

Since 1978, the Barn is used as setting for cultural events (theatre, concerts) and for family and association meetings...

Since 1991, it is the property of the commune.
