Solidor Tower

The Solidorturm stands on the banks of the Rance estuary in Brittany. It is a fortified keep made of granite, built between 1369 and 1382 by John IV, Duke of Brittany, to guard the river’s entrance. The tower has three linked cylindrical towers rising from a single base. It was meant to control ships entering the Rance when Saint-Malo refused to accept the duke’s rule. Over time the tower’s military role faded and it became a prison. The tower once housed a museum dedicated to Breton sailors who rounded Cape Horn. The museum closed in 2022 after decades of showing their stories. Before that, the building served as a jail for centuries. The Solidorturm also appears in the 1957 film True as a Turtle, adding to its cultural footprint. Its position in the former town of Saint-Servan links it to the larger history of the region. Visitors find a granite fortress with narrow staircases winding through its three towers. The views from the top over the Rance estuary stretch towards Dinard and Saint-Malo. The surrounding area includes the old centre of Saint-Servan, now part of the larger city. The tower’s stone walls and small windows recall its past as both a fortress and a prison. The estuary’s tides and shipping add movement to the scene.
