Sultan Barquq seized power in 1382, when Egypt was reeling from plague and famine; his Sufi school was completed four years later. Enter through the bold black-and-white marble portal into a vaulted passageway. To the right, the inner court has a lavish blue-and-gold ceiling supported by four porphyry Pharaonic columns. Barquq's daughter is buried in the splendid domed tomb chamber; the sultan himself preferred to rest in the Northern Cemetery, surrounded by Sufi sheikhs.
