Alcázar of Segovia, Spain. Segovia Castle, located in an ancient town of Segovia in central Spain, started off as an Arab fort in the 12th century. Its unique shape of the bow of a ship makes the fortress one of the most distinctive castles in the country. In the Middle Ages Alcazar was a key fortress in the defense of the country. Apparently, it was a source of inspiration for many of the castles produced by Walt Disney.
