A first church was probably built there as early as the 12th century. Nothing can be seen of it anymore, although the lower parts of the watchtowers at the corners of the east facade may still belong to the original building.

The place called “Sorbais” is mentioned for the first time in 1125 in the Chaourse cartulary. The first church was then built in the second half of the 12th century, after the municipality had considerably expanded in terms of area, which justified the construction of a church.
