The Alcázar of Segovia is a medieval castle located in the city of Segovia, Castile and León, Spain. The fortress is a World Heritage Site by UNESCO.

Rising out on a rocky crag above the confluence of two rivers near the Guadarrama mountains, 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 to serve as a fortress but has served as a royal palace, a state prison, a Royal Artillery College, and a military academy since then.

 It is currently used as a museum and a military archives building.
