The Dehesilla Tower is located in the countryside, very close to the El Negro and Garci Bravo estates. The main façade of the rectangular tower is about ten metres wide and six metres deep. A stone ashlar foundation supports its thick, rammed-earth walls that are over 7 metres high. The door on the north side still remains, framed by stone ashlars. The points where the barrel vault sprang from can yet be seen.
The tower is of Islamic Almohad origin. It was part of a defensive system together with other flanking towers found throughout the Aljarafe. Pottery remains from the Roman Imperial period, in particular, terra sigillata ware and amphorae, have also been found.
