Amazing Alcazar of Segovia

[Source]

The Alcázar of Segovia is a stone fortification, located in the old city of Segovia, Spain. The Alcázar of Segovia, like many fortifications in Spain , started off as an Arab fort, which itself was built on a Roman fort but little of that structure remains. 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. [Wiki]
