Chapelle de Nielles-les-Thérouanne

The last vestige of the former city of Thérouanne, destroyed in 1553, this church combines stone, brick and slate. It has a 16th-century nave and bell-wall, and a 17th-century choir and sacristy.

It is a must-see for pilgrims walking the cultural itinerary of the Via Francigena (GR145) linking Canterbury to Rome.
