Eglise Saint-Pierre d’Ault et Beffroi Ecclésiastique

Saint-Pierre church, built with a chequered design with white stone and cut flint, typical of the region, is the only one in Picardy with an ecclesiastical belfry resulting from the extension of a communal charter dating back to 1382. Recently discovered, it is the third in France, after those in Dunkirk and Cambrai. It is a listed building.
The 14th century bell tower is an imposing quadrangular tower with a flat roof, gargoyles at all 4 corners and 3 bells. A slender watch tower stands on the top. It was built at the same time as the church and became an ecclesiastical belfry during the Hundred Years War (charter of 1382).
