This building, located in the Plaza de la Iglesia, is made of lime, sand and local stones. Built towards the end of the 13th century, it is a solid structure with pointed architectural elements as well as Gothic elements from the 14th and 15th centuries. The floor measures 26 metres in width on the façade side and 56 metres in depth (24 metres under cover and 32 uncovered). The smooth and simple façade holds the only door, which features jambs and rounded arches with large voussoirs. In the upper section in the centre, above the entrance, is a square space that held this estate’s coat of arms, perhaps made out of tile. The façade contains three stone mullions (windows) and three pointed jambs. The one above the door, which held three trilobeds and a special type of mirror for aiming light, has unfortunately disappeared. These jambs stood on shelves and their upper end held up their own capital. This capital formed the beginning of the pointed arches.
The first room after the entrance has a 15th-century simple ribbed vault with a lowered arch. It corresponds to the style of artists from the first construction period. Of similar construction is the room which leads to the only staircase, which goes up to the rooms and bedrooms on the first floor’s intermediate level. Between the entrance lobby described above and the bedroom in front, which gives access to the covered area, is the rectangular patio de armas or patio de luces. To the right of the entrance is the room which would have been the bedroom or the side chapel when the church was still the aforementioned chapel.
Traditionally, when the lord sentenced a vassal to die on the gallows, a red flag was hung out of one of this tower’s windows to show the decree would be completed. The prisoner would be hung on the hill heading towards Santa Lucía, which is called the Monte de la Horca, or the Hanging Hill
