Culture
The Église Saint-Martin is located in Cilly, about 6 km east of Marle, and belongs to the group of fortified churches in Thiérache. Inside the church is a Belgian bluestone tombstone for the knight Ferri de la Bove, Lord of Cilly and Governor of Guise, who died in 1573. The year 1645 can be seen above the entrance to the Église Saint-Martin; it is probably considered to be the year when the church was fortified.
The wider region around Cilly is home to the Abbaye de Foigny monastery, as well as the historic sites Abbaye du Sauvoir, Abbaye de la Val-Roi, and Abbaye Saint-Jean de Laon.
