Cuerva Castle, locally known as Castillo de Cuerva, lies west of the village by the same name in the province of Toledo in Spain. It is also known as Castle Peñaflor.
Although there already was a castle at this site in the 12th century, the present castle probably dates back to the 15th/16th century.
It has a rectangular groundplan with circular towers, three stories high, in three of its corners. Only the north, west and south walls survived until this day. The foundations of these towers are the square towers, whhich had a larger size, of the earlier castle. This earlier castle was also rectangular but with square towers in its corners of which the southeast one served as a keep.
In the 15th century it belonged to Iñigo Vélez Guevara who received it from King Enrique IV. Shortly after that it was owned by Garcilaso de la Vega and by the end of the 16th century it had deteriorated and was abandoned.
The castle is situated only a few yards from the road leading from the village of Cuerva to Gálvez. It seems to have no use and it's freely accessible.
