Church of Notre-Dame de Bonport

Norman building with portal and porch from the 12th century, which was restored in the 16th century with a Gothic style presbytery and an exceptional lantern tower. The name Notre-Dame de Bon Port really calls to mind the maritime nature of the city. Also don't be surprised to find offerings to saints there and graffiti by sailors, as well as a collection of model boats.
Another 'must see' are the multi-coloured stained glass windows from the 15th century which evoke the history of the navigation on the Seine in the 18th and 19th centuries.
