St. Louis Cathedral
Place de Verdun, La Rochelle, France
Description:
The Cathedral of Saint-Louis was repeatedly mentioned by Alexander Dumas in his novels.
However, the cathedral, built in the 18th century, was never completed. There are marine exhibits, models of ships. The interior halls are devoted mainly to marine themes, while the architecture of the cathedral itself is more like a military fort of the Middle Ages.
In the courtyard of the cathedral, you can sit at tables and hide from the bustle of the city, as in the literal sense, behind a stone wall.
Nearby there are marine and oceanographic museums.
