The Église Saint-Martin de Wimy is a Catholic church located in the municipality of Wimy, in the east of the Aisne department. The church was built in the 16th century and is one of the finest examples of a fortified church in the region. The church has a massive donjon with a square plan and a double-pitched roof, flanked at the front by two enormous towers five meters in diameter, all in brick, except for the base of the towers in sandstone. The rest of the church, which extends behind the donjon, is a parallelogram of stone, with numerous restorations in brick. The church has been listed as a historical monument since 1989.

Locomobile No. 3003, which can be seen at the entrance to the town of Buire and the former railway depot, was manufactured in 1900 by the construction engineer Emile Salmson. Its operating pressure was 7 bars. Property of the Northern Railway Company, it was used to drive the machine tools of the Hellemes Workshops (North). As the SNCF machine tools became autonomous, she ended her career in 1939. It was Monsieur Raclot, director of the Leclerc center, who offered her second youth to the ECO-RAIL association.
