The Rocher de la Vierge (Virgin's Rock) is a natural tourist attraction shaped like a long ship's hull, topped by a statue of the Virgin Mary. It is an iconic landmark of the city of Biarritz in the Pyrénées-Atlantiques department. From the top of this rock, one can admire the entire Bay of Biarritz, its Grande Plage (Main Beach) on one side and, on the other, the Basque coast stretching to the Pyrenees.
