This hiking hotspot combines history, nature and architecture. Château d'Armentières is a medieval castle nestled in a valley near the Ourcq River. The castle dates from the 13th or 14th century and was modified in the 16th century. It belonged to two great French families: the Juvénal des Ursins and the Conflans d'Armentières. You can admire the remains of the High Court, the Noble House, the Gate Tower and the Horseshoe Tower, as well as the surrounding landscape. The castle is privately owned, but you can tour the exterior with a guided tour. Tours are offered occasionally from April to October for individuals and all year round for groups. The Château d'Armentières is a privileged place to discover the heritage and beauty of the Omois region.
