Dome

"This two-storied, brick historic monument is situated close to the left bank of the Tigris River in the al-Maiden neighborhood of Baghdad. While there is much contention over the original date of the site, stylistically it was probably constructed during al-Mustansir's caliphate, dating it to the late Abbasid period (1175-1230). Excavations and restoration efforts provide evidence that it most likely functioned as a madrasa rather than a palace."
