tretat is a municipality on the coast of the Upper Normandy region of France, often called the Elephant Trunk Coast. On the shore of Etreta, the three most famous sea-eating gates are Porte dAval, Porte dAmont, and Manneporte. The cliffs and connected beaches attract 19th-century French landscape painter Boudin, the realist painter Courbet, and Impressionist painter Monet to visit.
