Secondigné-sur-Belle, a village of a pop. about 500, hosts the pretty large church Saint-Pierre-ès-Liens, erected probably within the 12th century, but altered and enlarged later. There are quite a lot churches named "St. Peter in Chains" in Europe.

They all refer to St. Peter’s miraculous escape from prison - Acts 12:1-19. The chains are on display in "San Pietro in Vincoli" in Rome.
