ABSTRACT
The great palace of Mansur, in the centre of his Round City, was known as the Golden Gate or the Palace of the Green Dome; sometimes also it was named the Golden Palace. Its area covered a space originally measuring about 200 yards square, and its central building was crowned by a great dome, green in colour asKasready said, on the summit of which, at a height of 120 feet above the ground, and visible from all quarters of Baghdad, was the figure of a horseman. The Palace of the Golden Gate, however, appears to have been the official residence of Mansur and his immediate successors. Harun-ar-Rashid, it is true, preferred the Khuld and lived for the most part there when staying in Baghdad, but his son Amin again held his court in the Palace of the Golden Gate, where he is said further to have added a building of his own invention, probably some sort of pinnacle or belvedere.
