Billy
Eglise Saint Martin
Built from 1764 to 1767, the building has a Comtois bell tower-porch surmounted by an imperial dome, perhaps because of its proximity to Franche-Comté.
This bell tower contains a monumental clock in its upper part.
The church of Billey is named after a 4th century saint, extremely popular in his lifetime in Roman Gaul: he was renowned for healing the sick and raising the dead.
