The tower is locally known as 'La Tour des Prêtres' because it served as a prison for Catholic priests during the French Revolution.
It houses over 600 pieces of graffiti carved by prisoners, some dating back to the 17th century.
The interior contains an original spiral stone staircase leading to the upper gallery.
The tower was completed in 1468, replacing an earlier structure that burned down.
The spire's design represents the transition from defensive military architecture to religious or ornamental stone masonry.
The Lantern Tower, or Tour de la Lanterne, is the last medieval lighthouse on the Atlantic coast of France. Standing 55 meters tall, it is the tallest of the three historic towers guarding the entrance to La Rochelle's Old Port. Originally constructed in the 15th century, the structure features a late-Gothic architectural style with an octagonal spire. It served as a lighthouse for mariners and functioned as a state prison for several centuries. Visitors can observe over 600 graffiti carvings etched into the interior stone walls by imprisoned sailors and soldiers. The tower is connected to the city's old defensive ramparts. It remains managed as part of the National Monuments of France.

Climb to the top gallery for panoramic views of the harbor and the surrounding islands.
Wear sturdy, non-slip footwear to navigate the narrow and uneven medieval stone steps.
Combine your visit with the Saint-Nicolas and Chaîne towers, as they form the historic defensive triad of the port.
Do not attempt the climb if you have mobility issues, as the spiral staircase is steep, narrow, and potentially disorienting.
Closed on January 1, May 1, and December 25.
Maintain silence in narrow passages and avoid touching the historical graffiti carvings on the walls.
