Whether you have been walking up hill for a while, or just got dropped off by a tour bus, you will be excited when you reach Puerta de la Justica. Door of Justice has been the southern entrance to Alhambra since 1348 during the reign of Yusuf I. He was the Sultan of Granada from 1333 until 1354. The keystone of the first horseshoe arch has a marble relief of a hand. The fingers represent the Five Pillars of Islam (faith, prayer, giving, self-purification and pilgrimage). Near the other side of the tower is an inscription praising the Catholic Monarch for liberating Granada. This is the first of many times you will witness the contrasting impact the Nasrid and Spanish kingdoms had on Alhambra.
