Saint-Jean aux Bois Abbey

The church of Pierrefonds is dedicated to Saint Sulpice de Bourges, which allows us to conclude that it was founded from the end of the Merovingian period. A number of churches in the region are dedicated to the same patron saint.

The Church of Saint-Pierre-et-Saint-Michel of Séry-Magneval, in the Hauts-de-France region was built around 1200. The church is surprising because of its slender character, a characteristic that is rare for a church of such limited dimensions. It consists of a Romanesque nave that was exalted at the end of the sixteenth century, a transept and a choir that was built at the beginning of the thirteenth century in the Gothic style. The church retains traces of painted decorations of the twelfth, thirteenth, sixteenth and eighteenth centuries.

Church located between the castle and the former dwelling of the "Prémontrés". Construction of the church (dedicated to Saint-Maur) decided in the 12th century (choir, drip walls of the nave, transept crossing), continued in the early 13th century.
