Solidor Tower
From Wikipedia, the free encyclopedia
Solidor Tower (French: tour Solidor) is a strengthened keep with three linked towers, located in the estuary of the river Rance in Brittany.[1]

It was built between 1369 and 1382 by John IV, Duke of Brittany (i.e. Jean V in English) to control access to the Rance at a time when the city of Saint-Malo did not recognize his authority. Over the centuries the tower lost its military interest and became a jail. More recently it was a museum celebrating Breton sailors exploring Cape Horn, but it was permanently closed in 2022.
The Solidor Tower is located in the former town of Saint-Servan, which merged with Saint-Malo and Paramé in 1967.
It is featured in the 1957 Wendy Toye film True as a Turtle starring John Gregson, Cecil Parker, June Thorburn and Keith Michell.[2]
