Château d'Ailly, Medieval castle in Bernières-d'Ailly, France.

Château d'Ailly is a stone château at Bernières-d'Ailly, with a long, low facade of light grey and tan masonry under a steep brown tile roof. Two slightly projecting pavilions with matching tall chimneys flank the central block, whose windows have white shutters and whose doorway is reached by a short flight of stone steps. About a dozen rounded dormer windows pierce the roofline, and a small square pavilion with a pyramidal roof stands on the lawn before the left wing.

The original manor was founded around 1050 by Robert d'Ailly and protected by walls and moats. Around 1721, Charles d'Aubert d'Ailly undertook major renovations that transformed it into its current appearance.

The name Ailly comes from the Latin aillium, a property enclosed by walls. A church dedicated to Saint Gerbold, a 6th-century Norman saint, was built here in the 11th century alongside the manor. The estate stayed in the same families until its sale in 2007, and it remains a private property today.

The property is located in Normandy in the Calvados department and holds official heritage status as a registered historical monument. Access may be limited as the site is under special protection, so it is wise to check ahead about which areas are open to visitors.

During renovation work in 1832, nine Bronze Age helmets were discovered on the property, now known as the Ailly helmets. This archaeological find reveals that the area was inhabited long before the castle itself was built.
