The Alcázar of Segovia ("Segovia Castle") is a medieval castle located in the city of Segovia, in Castile and León, Spain. Rising out on a rocky crag at the western end of the old town, above the confluence of rivers Eresma and Clamores at the bottom of Sierra de Guadarrama, it is one of the most distinctive castle-palaces in Spain by virtue of its shape– like the bow of a ship. The alcázar was originally built around the eleventh century by the Almoravid dynasty to serve as a fortress and has subsequently served as a royal palace for twenty-two monarchs, a state prison, a Royal Artillery College, and a military academy. The Old Town of Segovia, including the alcázar, was declared a UNESCO World Heritage Site in 1985. Today, it is used as a museum and a military archives building since its declaration as a National Archive by a Royal Decree in 1998. History The Alcázar of Segovia, like many fortifications in Spain, started off as a Roman castrum, but apart from the foundations, little of the original structure remains. The alcázar was built by the Berber Almoravid dynasty. Almoravid art and architecture is scarcely talked about in scholarship in part because so little of the physical work has survived in Spain. Furthermore, the Almoravid dynasty was short-lived and therefore much of the art and architecture of that period was subsequently destroyed or converted by their successors. The first reference to this castle was in 1120, around 32 years after the city of Segovia was conquered by the Christians (during the Reconquista when King Alfonso VI reconquered lands to the south of the Duero river, down to Toledo and beyond). In 1258, during the reign of King Alfonso X of Castile (r. 1252–1284), an intense thunderstorm caused a fire that destroyed several rooms, leading to centuries-long reconstruction during the reigns of various kings. The shape and form of the Alcázar was not known until the reign of King Alfonso VIII (1155–1214), however early documentation mentioned a wooden stockade fence. It can be concluded that prior to Alfonso VIII's reign, the Muslim era structure was no more than a wooden fort built over the old Roman foundations. Alfonso VIII and his wife, Eleanor of England (sister of Richard the Lionheart), made this alcázar their principal residence and much work was carried out to erect the beginnings of the stone fortification we
