Aleth Cathedral

Solidor Tower (in French tour Solidor) is a strengthened keep with three linked towers, located in the estuary of the river Rance in Brittany. It was built between 1369 and 1382 by John V, Duke of Brittany (i.e. Jean IV in French) 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. It is now a museum celebrating Breton sailors exploring Cape Horn. 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.

Saint-Malo Cathedral (Cathédrale Saint-Vincent-de-Saragosse de Saint-Malo) is a Catholic Cathedral located in Saint-Malo, Brittany, France. The church was founded in dedication to Saint Vincent of Saragossa and is a national monument of France. It was built in a mix of Romanesque and Gothic styles during the episcopacy of Jean de Châtillon (1146-1163) on the site of an ancient church founded in the 7th century. The cathedral suffered damage during World War II when the steeple toppled onto the Sacred Heart Chapel. An organ which had been built in 1893 by Louis Debierre was destroyed. On 21 May 1972, after 28 years of work, a ceremony was held to celebrate the completion of the restoration. It is a stop on the Tro Breizh, a Catholic pilgrimage that links the towns of the seven founding saints of Brittany.
