Saint Peter Paul from the 11th to the 16th century. It is a Vexin church rich in curiosities in a great architectural sobriety. It preserves, in a remarkable early Romanesque style, capitals of pillars adorned with animals, plants and human heads. It presents a mixture of styles ranging from Romanesque to Gothic Flamboyant with a beautiful harmony in a compact plan. A spacious nave of the 11th and 12th century with slightly pointed arches, a Gothic choir of the 13th century and a bell tower of the 16th century. On the hillside between fields and groves its bell tower points and indicates the hidden village Arronville and invites you to visit.
