Today occupied by the community of the Sisters of Mary, it was built in granite masonry work in the 16th century. Its Renaissance front, with details in Gothic style, is of particular interest. It boasts a semi-circular arch with large voussoirs under a window in the shape of an ogee arch with a storiated embrasure. The unit is set in a moulded panel frame and there are coat of arms on the sides.
It was designated a National Monument in 1992.
