The Tercia Real de Mota del Cuervo, also known as Casa de Bastimento, is one of the oldest buildings in the town, along with the parish church of San Miguel. Built at the beginning of the 16th century, this building was used to store the tithes of the Mesa Maestral of the Order of Santiago.
The building has a rectangular floor plan and is covered with four sides. It is built of masonry with ashlars in the corners and in the two entrance doors. One of the doors is finished with a segmental arch and the other with a semicircular arch on which a coat of arms is placed.
Currently, the Tercia Real is used as a cultural centre, where various temporary exhibitions and cultural events are held.
