Tour de la Chaîne

Tour de la Chaîne is a medieval fortification standing at the harbor entrance, built from thick stone with narrow defensive openings that once guarded maritime traffic. A massive chain system linked this tower to its partner structure across the water, creating a barrier that ships had to pass through.

This fortification was built in the late 14th century to defend La Rochelle's harbor entrance, working with a partner tower to control who could enter the port. In the 17th century, a major explosion damaged it significantly, leaving marks that remain visible in its interior layout today.

The tower reflects La Rochelle's deep connection to maritime trade and defense, with its fortified design telling the story of a port city built around the sea. Inside, the thick walls and narrow passages show how residents organized their work to safeguard the harbor entrance.

The tower is open to visitors during the warmer months, and climbing to the upper levels involves navigating stairs, some of which lead to surprising dead ends. Being right at the harbor, the site can be quite windy, so comfortable walking shoes and a light jacket are practical choices.

Several stairwells inside lead to rooms that are now sealed off due to damage from centuries past, leaving visitors to discover dead-end passages unexpectedly. These abandoned sections offer a hidden view of how much violence the structure actually endured.
