Tour de la Lanterne (Lantern Tower), La Rochelle

The Lantern Tower is a remarkable blend of medieval architecture, maritime history, and somber remembrance. Originally constructed at the end of the 12th century, the tower stood at the entrance to the old port, where it played a vital defensive and regulatory role. The resident captain, known as “the ship disarmer”, was tasked with ensuring that vessels entered the port without weapons. This early version of the tower laid the foundation for what would become one of La Rochelle’s most iconic structures.

Significant modifications to the tower took place in the 15th century. Between 1445 and 1468, under the leadership of Mayor Jehan Mérichon, a larger Gothic-style tower was built around the original one. The vaulted ceiling of the lower hall was preserved, and the new tower was crowned with a 30-meter-high stone spire, atop a 25-meter cylindrical base. Designed to function as a lighthouse, the tower’s lantern — a glass-enclosed flame — served as a crucial beacon for sailors, giving the tower its current name.

From the 16th century onward, the Lantern Tower took on a darker role as a prison. It housed a wide range of captives over the centuries: foreign privateers, Protestant detainees after the revocation of the Edict of Nantes in 1685, and Vendée rebels during the French Revolution. The tower even witnessed tragic events during the Wars of Religion, including the execution of thirteen Catholic priests in 1568. Inside its walls, over 600 graffiti etched by prisoners still remain, providing a haunting, personal record of those who passed through. Among the most notable is a detailed carving by a man named Lafontaine in 1872, depicting a ship sailing between towers.

Today, the Lantern Tower stands as a 55-meter-high testament to La Rochelle’s layered past. Visitors can explore its thick stone walls, admire the preserved medieval graffiti, and ascend to the gallery at the top of the spire. From there, panoramic views reveal the old city and the Atlantic Ocean beyond — a fitting vantage point from which to reflect on the tower’s long and complex history.
