Chinguetti 7th is the holiest city of Islam, and ancient caravan. The pilgrims from West Africa came together to Oulata Chinguetti before returning for a final journey to Mecca. Behind the walls of ocher Chinguetti in the Sahara Desert, waves of sand from white to red come crashing against the sandy island. The city was founded in the late 13th century. Located on the main caravan into a true megalopolis of trans-Saharan trade, the Ksour (stronghold in Arabic) had established regular trade with the Maghreb, Egypt and Arabia, at the same time affirming their rites in the Arabic and Islamic culture .
