The Mosque and Madrasa of Sultan Hassan, built between 1356 and 1363, is considered the masterpiece of Mamluk architecture. Its sheer scale is overwhelming from outside: the facade rises 38 metres, and the carved stone portal is 20 metres high. The proportions are perfect in a way that no photograph quite captures.
Inside, four great iwans (vaulted halls) face a central courtyard — each iwan housing one of the four schools of Sunni Islamic law. The prayer iwan at the far end, with its forest of hanging brass lamps and its deep mihrab niche, is one of the finest interior spaces in Cairo. The attached mausoleum holds the sultan's cenotaph. The mosque stands just below the Citadel; the view back up toward the Saladin fortress from the mosque's entrance is one of Cairo's great urban compositions.
