Most religious facades in Granada have meaning. The door of the Monastery of Santa Isabel la Real is no exception. The eagle in the center is the coat of arms of the Catholic Monarchs. The yoke on the left represents Queen Isabella I of Castile. The crossed arrows indicate Ferdinand II of Aragon. The knotted cord symbolizes the Franciscan vows of poverty, chastity and obedience. The Poor Clares tie a fourth knot showing their dedication to secluded prayer.
