Rocamadour is one of the most visited sites in France and has been an important centre for Christianity ever since the Middle Ages. It can be very busy in summer but makes an interesting day out. The holy city clings to the steep rocky cliffs, displaying layer upon layer of houses and chapels. Down from the castle which crowns this construction, there is a sheer drop of some 150 metres. The basilica of Saint-Sauveur and the crypt of Saint-Amadour are both featured on UNESCO’s World Heritage List. The jewel of the sanctuary is kept in the Chapel of Miracles, one of eight chapels built against the rocks. It is the Black Madonna, which has been worshipped here for over a thousand years.
