The Towers of La Rochelle are two iconic towers located in the city of La Rochelle, France. They are situated at the entrance to the Old Port and have been designated as a national monument since 1879.

The taller of the two towers is known as the Tour Saint-Nicolas and was built between 1375 and 1382 to defend the city against English attacks during the Hundred Years' War. It stands at a height of 42 meters and has a diameter of 20 meters at its base.

The other tower is known as the Tour de la Chaîne, and it was built between 1382 and 1402 as a complement to the Tour Saint-Nicolas. It stands at a height of 34 meters and has a diameter of 18 meters at its base. The name of the tower comes from the chain that was once used to block the entrance to the port.

Today, visitors can climb to the top of the towers to enjoy stunning views of the city and the Atlantic Ocean. The towers also house a museum where visitors can learn more about the history of La Rochelle and the role that the towers played in its defense. The Towers of La Rochelle are a popular tourist destination and are considered to be one of the most important historical sites in the region.
