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

Beautiful walk among the thatched cottages and in the forest. This route, rather flat, is accessible by mountain bike because the paths are passable.

The Saint-Ouen church in Pont-Audemer, imposing although unfinished, is one of the foremost monuments of flamboyant Norman architecture.
