Introduction to the ancient castle: The ancient castle of Toledo is located at the commanding heights of Toledo. In the mid-16th century, it was the palace of King Carlos V. The castle is square in shape with four square spire towers at the four corners. Climbing the tower you can see all around and have a panoramic view of the scenery far and near. For hundreds of years, this castle has carved various marks in the history of the Spanish nation. The three-year civil war that broke out in 1936 was also one of the important battlefields. The numerous bullet marks around the castle can still be vaguely discerned. .
