Port-Marie Beach, Îles Chausey

The granite from Chausey Islands was quarried for over 800 years, from the 11th century until the 1940s. This stone was used to build Mont-Saint-Michel Abbey, reconstruct Saint-Malo after World War II, pave Paris sidewalks, and construct London port quays. At its peak in the 19th century, around 500 quarry workers lived on the islands, and ruins of their houses remain visible on 37 islets today.
