Commanderie d'Arville, Medieval Templar commandry in Couëtron-au-Perche, France.

Commanderie d'Arville is a former Templar and Hospitaller commandry on the slope of a hill beside the Couëtron stream in Couëtron-au-Perche, Loir-et-Cher. Its entrance is a stone gatehouse with a large round-arched passage, two small shuttered windows above, and a round tower with a slate conical roof on each side. The 12th-century church and the base of this porch are the oldest standing parts.

The Templar house of Arville was founded in the 12th century on land given by a lord whose identity remains uncertain, on a hillside above the Couëtron stream. Templar presence is confirmed from 1169, when the canons of Notre-Dame de Chartres and local lord Rahier de Montigny agreed to share land revenues with the "Templarios de Arevilla". The estate became a full lordship with high, middle and low justice, and its surpluses were sent to the Temple treasury in Paris.

The site carries the name of a medieval religious order and shows how visitors can today understand the spiritual life of that era. The buildings themselves tell through their layout about the daily work and priorities of that period.

The commanderie lies on the slope of a hill beside the Couëtron stream, 11 km from Mondoubleau and 37 km from Vendôme, in the commune of Couëtron-au-Perche. The buildings stand within an enclosure entered through the gatehouse, so allow time to walk between the church, the agricultural buildings and the dovecote.

The estate's prosperity at the end of the 13th century is documented by deposits made to the Temple treasury in Paris: the preceptor of Arville handed over 755 livres and 39 sous in July 1295, February and July 1296. A miller brother is named as witness in a deed at Arville in 1209.
