This UNESCO Heritage site was originally built by the Romans as a fort and later improved by the Muslims.  Christians took it in 1120 and made a series of improvements, after many centuries the castle served as the Capital of Leon and Castile with Queen Isabelle enthroned after the death of King Henry IV in December, 1474.  The intricately beautiful patterns within the interiors of this iconic, ship bow shaped alcazar are impressive and demonstrate the Muslim influence on the region as well as the importance of symmetry and geometry in design.
