Although first mentioned in 1540, the Cingle fortified house was undoubtedly built in the second half of the 14th century by the Pèlerin family. Originally composed of a main tower and a wing back to the west, it perhaps originally included a curtain wall. During the 15th century, the south wing was extended towards the west, a main building comprising a lower room and an upper room was attached to the north of the main tower, while a turret occupied on the first floor by an oratory and on the second by a dovecote is built to the east, projecting. A wing including the kitchen on the ground floor is also built at right angles to the north of the courtyard. The farm itself retains some architectural elements dating from the 16th century.
