Completed in 1363 this mosque and school symbolizes the power of the Mamluk sultans. Its initiator was Hassan, the energetic (7th) son of Mohamed Hassan. Perhaps in a hurry to leave his mark on the world - assassinated at the age of 27- he chose an ambitious project. The main building is 150 meters long, 68m wide and 36m high. A colossal structure even now, let alone if placed in the 14th century context. The ornamentation is perhaps not as refined as other examples of Mamluk architecture, but still awe inspiring.
