Medina of Essaouira (formerly Mogador)

Essaouira is an exceptional example of a late-18th-century fortified town, built according to the principles of contemporary European military architecture in a North African context. Since its foundation, it has been a major international trading seaport, linking Morocco and its Saharan hinterland with Europe and the rest of the world. [source]
