Loarre Castle is a fortress in Loarre, Spain.
Also a location of the Hollywood Movie Kingdom of Heaven (2005)
The complex was built largely during the 11th and 12th centuries, when its position on the frontier between Christian and Muslim lands gave it strategic importance. The first of the two major building programs began ca. 1020, when Sancho el Mayor (r. 1063–94) reconquered the surrounding lands from the Muslims. At least three towers, two of which survive, the keep (Torre del Homenaje) and the "Tower of the Queen" (Torre de la Reina), as well as a chapel dedicated to Saint Mary of Valverde and connecting walls are attributed to this campaign. The keep was built in an isolated position in front of the fortifications, to which it was connected by a wooden bridge. It contained a basement and five floors. The Torre de la Reina, comprising a basement and three floors, is particularly noteworthy for three sets of twin-arched windows, with columns of exaggerated entasis and trapezoidal capitals that have been related to both Lombard and Mozarabic architectural forms. The chapel is composed of a single-cell nave with an eastern apse covered by a semicircular vault. The original timber roof of the nave was replaced by a vault at the end of the 11th century.
