Alcázar de Toledo Castle is located on a rock at the highest point of the city. Throughout history, he performed an important military function. The building currently houses the Museum of the Spanish Army and the Public Library of the Castilla-La Mancha region. There are also office rooms.
The castle was built in Roman times for defensive purposes. Throughout its history, it underwent many modernization efforts that softened its fortress character. The building in its current shape is characterized by strong Renaissance influences, in particular the facade. The castle was a critical resistance point of the Civil Guard during the Spanish Civil War. It was also damaged at that time, which was repaired in the second half of the 20th century.
