Eglise Saint-Léger et Sainte-Agnès d'Agnetz

The Chapel of Saint-Jacques and Saint-Christophe d'Auvillers is located in Neuilly-sous-Clermont. The chapel, has pre-Romanesque features, such as a single nave opening onto a flat chevet choir, that was later rebuilt in a primitive Gothic style. It is surmounted by a stone belfry with an octagonal slate spire. The chapel housed a white Carrara marble bas-relief: "The Madonna of Auvillers" by Augustine said Duccio (fifteenth century), that has now been replaced by a copy after the original was moved to the Louvre.

Built of dressed stone, it is a small building that has been extensively altered and renovated over the centuries: the bell tower, the choir and the underside of the bell tower, vaulted in the 16th century, bear witness to this.

The Saint-Martin church was built in the 12th century in Heilles and is surrounded by the old parish cemetery. The church, which is dedicated to St. Martin of Tours follows a cruciform plan. It consists of a Gothic porch opening to the west entrance, a single Romanesque nave (12th century), an overflowing transept whose cross serves as a base for the bell tower and a choir (13th century) composed of a very short span and a seven-sided apse.
