Kasbah Museum

This is a museum where the architecture is as much of a draw as the exhibits. Housed in Dar el-Makhzen, a former sultan's palace on the edge of the medina, the institution features a traditional courtyard garden and contains exhibits on the history of Tangier, from prehistory to the great Islamic dynasties that forged Morocco. The best part? The spectacular floor mosaics from the Roman city of Volubilis.
