Dome

"Built in 1361-63, the cruciform madrasa of Amir Mithqal al-Anuqi was dedicated to the Shafi'i rite. The desire to impose formal architectural planning on a constricted irregular site produced an inventive scheme in which symmetry is achieved by a modified and attenuated four-iwan plan. An unusual engineering feat is the suspension of the whole structure over an alley, producing a hanging madrasa."
