This modest church has a crypt with strange properties. Built in the 14C on a small mound and surrounded by a cemetery, it was remodelled in the 19C. In the 17 and 18C, it served as the tomb for eleven people. The bodies were preserved from decomposition by an "antimony" gas which came out of the ground: four of them are exhibited under glass. To illustrate this phenomenon, several birds including a parrakeet have been hung in the vault.
