Butte Chaumont, Natural hill in Orne, France.

Butte Chaumont is a forested hill in the Écouves forest northwest of Alençon, in the Orne department. It rises to 378 metres between the Signal d'Écouves and the Mont des Avaloirs, within the Armorican Massif. Its rounded, gently sloping summit is covered in dense green vegetation, with a small raised point near the centre of the crest.

During the First World War, in 1916, Butte Chaumont was chosen as one of the high observation posts on a line running from Brest to beyond Lyon, to watch for German aircraft and airships. In 1917 Sergeant André Bouton, later historian of Maine, was ordered to build a wooden watchtower on the summit and house his troops in a wooden barracks. He never saw an enemy plane, but his stay led to his first research and to his 1924 book on the site. The hill was classified as a protected site on 17 November 1931.

André Bouton, a sergeant in the 117th Infantry Regiment, was posted here in 1917 to build a watchtower and house his unit in a wooden barracks, watching for German aircraft and airships. His stay led to his first research and to a 1924 book on the site, Les environs pittoresques d'Alençon : la Butte-Chaumont.

The area is protected and visitors should follow marked paths to avoid disturbing wildlife and vegetation. Wear proper hiking boots and be cautious in wet weather, as the ground can be slippery.

In 1916 the summit was chosen as one of the high lookout posts on a line running from Brest past Lyon, watching for German aircraft and airships. Sergeant André Bouton, later historian of Maine, built a pylône here in 1917 and lodged his troops in a wooden barrack; he never saw an enemy plane, but began the research that led to his 1924 book on the Butte-Chaumont.
