Palace built around a primitive medieval tower, that of San Xurde, owned by the lords of Aguilar and cited in ancient documentation as Castro de Aquilare.

The palace is a rectangular-plan construction, with two floors, developed around the tower, dating back to the 18th century. It houses a rich archaeological collection, assembled by Ricardo Duque de Estrada, one of the pioneers in Asturian archaeological studies between the late 19th and early 20th centuries. It was declared an Asset of Cultural Interest in 1991.
