Church of Saint-Nicolas, Ferte-Milon

This church was originally called the Chapelle Fouquet and was part of the great enclosure of the castle. At the request of the Milonais, who found the Chapel of Saint-Waast too far from the upper town, Catherine de Médicis had a semi-circular chevet sanctuary with five windows adapted by the architect Philippe de l'Orme (architect of the Louvre) in 1563.

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.

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.
