Elder Miller said this was a model for the castle in 'Sleeping Beauty.' It also had cool texture on the walls, and that one little window which seems to show the Muslim influence from Spain’s past. This castle used to be a main royal residence, and it was from this castle that Isabella the Catholic left to be proclaimed queen, on the Main Square of Segovia on December 13th, 1474 (according to the pamphlet I snagged). Then the Court moved to Madrid and the castle was used as a state prison and then housed the Royal Artillery School.
