A massive iron chain was stretched between this tower and the Tour Saint-Nicolas to create a physical blockade across the port entrance.
The tower features a distinct vaulted ceiling constructed in a ribbed gothic style.
During the 17th century, the tower served as a prison for Huguenots during the French Wars of Religion.
The tower's masonry exhibits marks from medieval stonecutters used to track the work completed by different artisans.
It is one of three remaining towers from the original medieval fortification wall of La Rochelle.
The Chain Tower (Tour de la Chaîne) is a 15th-century maritime fortification located at the entrance to the Old Port of La Rochelle. It served as a strategic defensive point, once linked to the Saint-Nicolas Tower by a massive chain that was raised at night to control harbor access. The structure is part of a complex of three historical towers that protected the city against English naval incursions during the Hundred Years' War. It is currently operated as a museum detailing the city's history, the protestant uprisings, and maritime trade. The interior features vaulted stone architecture and exhibits spanning multiple floors. It is officially managed under the Centre des monuments nationaux. The tower sustained significant damage during the 17th-century Siege of La Rochelle but was subsequently restored.
