Baghdad, Iraq
The capital of the Muslim world, as well as a centre of learning and trade, Baghdad quickly grew to be one of the largest cities in the world, if not the largest. Founded in 762AD on the western bank of the Tigris river, the city was planned to be a round circle with a diameter of approximately 2 kilometres and featuring a mosque as the focal point.
The city expanded rapidly beyond this, attaining a rich and diverse culture of people from different backgrounds and social classes. The markets of Baghdad were vibrant with international trade and inspired the many stories from Thousand and One Nights.
