Two fine old madrassas (schools where Islamic law is taught) face each other across a narrow alley less than 100m northwest of the Umayyad Mosque. Both of these schools were erected in the 13th century during the ascendancy of the Ayyubids. On the left (west), Madrassa al-Adeliyya was begun under Nureddin and continued under a brother of Saladin, Al-Adel Seif ad-Din, whose grave it contains. Its façade is considered a classic example of Ayyubid architecture.
