Wetter ile d’Oleron is a strait located in the southwestern part of France. It separates the island of Oleron from the mainland. The strait is about 4 miles wide and has a maximum depth of about 30 feet. It is an important shipping lane, as it provides access to the port of La Rochelle.
The strait has a long and rich history. It was first used by the Romans, who built a bridge across it. The bridge was destroyed by the Visigoths in the 5th century, but it was rebuilt by the French in the 12th century. The strait was also used by the British during the Hundred Years’ War. In the 16th century, the strait was fortified by the French to protect it from attack. The fortifications were expanded in the 17th and 18th centuries.
