Auvers-sur-Oise (Chaponval /
Le Valhermeil), Ile-de-France France
[Roman Catholic]
The chapel, probably build in the early 1200s, was part of the St-Nicolas d'Auvers leprosarium. The chapel was still in use during the early 1700s. In 1819 a new chapel was built nearby. The ruins have been protected since 1948.
