The land it now occupies must have been the site of important fortifications since antiquity given that the water pipes from the aqueduct finish in the Alcázar.

On the site of successive Roman, Visigoth, Arab and Christian fortifications, the Trastamaras built this majestic castle-cum-palace in the 15th century, which was later reformed and expanded with French and Italian influences. Isabel left the Alcázar in 1474 to be proclaimed Queen of Castilla.

Charles III installed the Royal Artillery College, which was destroyed in the fire of 1862. In 1882 it was rebuilt first becoming the General Military Archive and then the Artillery Academy and Museum.

Its prisons held nobles such as Don Alvaro de Luna and other imaginary figures like ‘Don Torcuato’ (from El Delincuente Honrado de Jovellanos).
