A fortress to defend the Duchy of Burgundy

Perched on a rocky outcrop overlooking the Cure River, the Château de Chastellux initially served a defensive purpose. Protected from attacks in this way, it was an important strategic stronghold.
Located on the border between Burgundy and the Nivernais region, the castle served as a base in the Middle Ages for armies sent to defend this gateway to Burgundy, which was then an autonomous duchy and often at odds with France.
A castle with stunning architecture
Built on the site of an ancient Roman fortification, Chastellux’s long history and its continuity within the same family explain the architectural diversity of the castle, which consists of an 11th-century tower, a 15th-century section, a 17th-century section, and, finally, a 19th-century tower and other elements.
The rock on which the castle is built is triangular in shape; this required the architects to demonstrate great skill in creating this curved roof.


During the Restoration, César-Laurent de Chastellux set out to restore the estate. Life then slowly returned to normal.
The château suffered another tragic event on May 30, 1975: a fire broke out in a chimney flue and set the roof and attics ablaze. The Amboise Tower still bears the scars of this fire, as evidenced by its missing roof. The current owner is continuing the restoration work begun by his predecessors, using traditional techniques, and is committed to preserving the castle’s authentic character while keeping it firmly rooted in its history and looking toward the third millennium.
