There is no precise information as of when this castle was built, but there is archaeological evidence that suggest that the site occupied by the Alcazar de Segovia, was once used as a fortification in Roman times. The first reference made to it was on the year 1120.
This castle/palace was renovated and expanded several times. Early documentation, mention that during the reign of King Alfonso VIII (1155–1214), this building was not more than a wooden fort built on top of the old Roman fort foundations.
In 1258, some parts of the Alcázar had to be rebuilt after a landslide, and also changes were made to house the Parliament. However, the major contribution to the construction of the Alcazar, was done by King Juan II, who built the “New Tower”.
The next major update of the Alcázar was conducted by King Felipe II, after his marriage to Anne of Austria, where he added the sharp slate spires to reproduce similarity to the castles of central Europe.
The interior of the Palace was decorated in a variety of ways including Romanesque, Gothic, Mudejar (Moorish), and Renaissance style.
It’s had many uses throughout history, having served as a royal palace, headquarters of the Spanish Artillery Academy, state prison, and now as a museum and home to the Spanish military general file.
