Built in the Gothic style, the 14th century tower is attached to the Saavedra House. Its two Gothic windows are worthy of special attention: the first has an ogee arch supported by columns enclosed in a rectangular frame, while the second has a round arch decorated with the Sande coat of arms. The façade is adorned with a coat of arms depicting five fleurs-de-lis, representing the Aldana family. It is now home to a restaurant.
