Interesting solution for the pedestrian path over the bridge

If we encounter the patronage of a Saint Thomas, then for most people outside Great Britain, their thoughts probably go back two thousand years to the time of Christ. This is because one of the twelve apostles whom Jesus called to follow him bears this name. In the accounts of the evangelists, he is given the epithet 'Didymus', which means 'twin' in German. However, in this case, the chosen patronage refers to Saint THOMAS BECKET (1118 to 1170), also known as THOMAS of CANTERBURY after the place of his bishopric and martyrdom. Incidentally, Canterbury Cathedral (County Kent, England) can be visited – at least virtually in the komoot system – via the following link: =>> https://www.komoot.com/de-de/highlight/231266
