Barcience Castle, locally known as Castillo de Barcience, lies next to the village by the same name in the province of Toledo in Spain. From the 11th/12th century there has been a castle at this site. It belonged to the Order of Santiago in the 13th century. The Order gave the castle to Don Alfonso Tenorio who passed it on to the Count of Cifuentes; the Silva family.
Erected on a small elevation of the terrain, it consists of a orthagonal main body, with two circular towers in the Western corners and two square towers in the Eastern corners, with the NE one being the largest one. One of the towers displays a relief depicting a lion rampant, the sigil of the house of Silva.
Despite the status of Bien de Interés Cultural via the generic 1949 decree in Spain for the protection of the castles of Spain, the building has been left in a situation of complete abandonment by the owners, losing pieces of the structure and enduring graffiti.
