Solidor Tower
Solidor Tower is a late 14th-century strengthened keep composed of three linked towers set at the mouth of the Rance estuary in Brittany. Built 1369–1382 by John IV, Duke of Brittany, it later served as a jail and in modern times housed a museum until 2022. The tower stands at the former town of Saint-Servan, now part of Saint-Malo.

As it stood in 1382
What Solidor Tower looked like in its prime.
A compact, triangular composition of three linked cylindrical stone towers rising directly from a low rocky islet at the estuary edge; thick, roughly dressed grey-brown masonry with a continuous corbelled band and machicolations beneath the parapet; the tallest tower capped by a steep slate roof; the structure linked to the quayside by a short stone arched causeway; tidal harbour and mudflats around the base, no later accretions visible in the prime state.
Its story
The story of Solidor Tower.
Solidor Tower — a strengthened keep of three linked towers — was built between 1369 and 1382 by John IV, Duke of Brittany, to control access to the Rance estuary at a time when the city of Saint-Malo did not recognise his authority. It stands in the former town of Saint-Servan, merged into Saint-Malo in 1967.
Over the centuries the tower lost its military interest and became a jail. More recently it housed a museum celebrating the Breton sailors who rounded Cape Horn, permanently closed in 2022; the tower also had a turn on screen in the 1957 film True as a Turtle.
