Église Saint-Martin

Built between 1764 and 1767, the building has a Comtois bell tower surmounted by an imperial dome, perhaps because of its proximity to Franche-Comté.

The bell tower features a monumental clock at the top.

The church in Billey bears the name of a fourth-century saint who was extremely popular in Roman Gaul during his lifetime: he was reputed to heal the sick and raise the dead.
