Buranlure, Medieval castle in Boulleret, France

Buranlure is a fortress in Boulleret, Cher, built from the late Middle Ages into the Renaissance. A semicircular lower courtyard holds a dovecote, stables and barns; a single-arch stone bridge replaced the drawbridge in the 18th century. Entry to the inner courtyard passes beneath a square tower, and the 15th-century building opposite is split by a stair turret.

Buranlure was a stronghold of the de Bar family, vassals of the Count of Sancerre, and served as a base for the king's troops during the Hundred Years' War, notably after 1420 when Anglo-Burgundians held Cosne. In 1573 Antoine de Bar raised a troop to support Maréchal de La Châtre at the siege of Sancerre. The Perrinet-Langeron family bought it in 1769 and turned it into a farm, which spared it later alterations. Arnaud de Vogüé, their descendant, began restoration in 1944, the year it was classified as a monument historique.

The name Buranlure comes from the de Bar family, lords of the seigneurie dependent on the Count of Sancerre. In 1769 the Perrinet-Langeron family bought the estate for its pastures and turned the castle into a farm, which it remained until the early 20th century. The castle has served as a film set, for Jacques Demy's Parking (1985) and Roger Planchon's Dandin (1988).

Buranlure is open to visitors in July and August and during the European Heritage Days. Access to the inner courtyard passes under a square tower, reached by a single-arch stone bridge built in the 18th century to replace the drawbridge. The castle stands in the commune of Boulleret, in the Cher.

The castle has served as a film set several times: Raoul Sangla's Le Grand Inquisiteur (1979), Jacques Demy's Parking (1985), Roger Planchon's Dandin (1988), a 2005 Three Musketeers TV film and Jo Baier's Henri 4 (2010). Visitors can look for the courtyard and towers used as backdrops.
