Kasbah of Marrakesh (The citadel, the walls, the gates and the royal palace of the city) is the historical heart of the old city of Marrakesh, Morocco. It was first built in the late 12th century AD by Caliph Ya'qub al-Mansur, who was the third Almohad Caliph. The Kasbah was later restored and rebuilt by the Saadian dynasty in the 16th and 17th centuries. Among the most important monuments of the Kasbah there are the El Badi Palace, the Kasbah Mosque, the wall and the gates (Bab Aghmat, Bab Agnaou, Bab Doukkala). Kasbah of Marrakesh was inscribed as a UNESCO World Heritage Site in 1985 as part of Medina of Marrakesh.
