When we encounter the patronage of Saint Thomas, most people outside Great Britain probably think involuntarily of the time of Christ, some two thousand years back. This is because one of the twelve apostles whom Jesus called to follow him bears this name. In the Gospels, he is known as "Didymos," which means "twin" in Greek. In this case, however, the chosen patronage refers to Saint Thomas Becket (1118–1170), also known as Thomas of Canterbury after the place of his episcopal see and martyrdom. Canterbury Cathedral (Kent, England) can be visited—at least virtually—via the komoot system at the following link: =>> https://www.komoot.com/de-de/highlight/231266

The 3 bridges between Le Havre and Rouen (Normandy, Tancarville and Brotonne (the latter quite dangerous for bicycles) are very high because they have to allow passage of large tonnage boats intended to supply Paris, the Seine being an important component. These boats are then unloaded in Rouen onto smaller tonnage boats which go to Paris. This system of ferries, surprisingly free, is therefore there to compensate for this lack of possible crossings. Do not hesitate to use them, it is really a very nice plus.

To avoid the extremely high bridges over the Seine, we chose the ferry. We enjoyed the crossing – completely uncomplicated and pleasant. I took photos of the departure times.

A large wooden hall, a sheltered place to stop on your journey, with benches, a water point, and a tire inflator with all valves, all across from the grocery store and the café "Chez Claudine" on the town hall square... Designed for cyclists and other hikers ♥️🔥 >> also added to freetaps, the water point app 🚰

The bridge itself is magnificent and it is also the only one in the region with a large cycle path and light traffic.
