Origin and history

Heilly Castle, situated on horseback in the communes of Heilly and Ribemont-sur-Ancre (Somme), was a hybrid building combining feudal and classical elements. According to legend, he would have welcomed Ganelon, character of Roland's Song, judged and executed in 778 after the battle of Roncevaux. This place was for centuries the heart of the seigneury of Heilly, whose lords took part in major events such as the battles of Bouvines (1214) and of Azincourt (1415).

In the 18th century, the Marquis Louis-Charles de Gouffier undertook an ambitious reconstruction under the direction of architect Pierre Contant d'Ivry. The castle was rethought in a neo-classical style, with a stone facade replacing the medieval walls, while the rear kept its towers and ditches. A large park, adorned with iron grids forged by Jean Veyren, was complete. The interior, rearranged in a rock style, included sumptuous living rooms, a chapel, and seigneurial apartments.

The castle was partially destroyed after its sale in 1848. Its decorative elements — grills, woodwork, sculptures — were dispersed: some of the grids now adorn the castles of Bertangles and Digoine, while statues of Nicolas Sébastien Adam, such as Angélique and Médor, are preserved at the Picardie Museum in Amiens. An 18th century pavilion, the last significant vestige, remains in a precarious state.

Since 2001, the remains of the estate (terraces, orangery, canals) have been listed as historical monuments. A digital reconstruction in virtual reality, proposed since 2021, allows to rediscover the castle in its eighteenth century state. The site, shared between private owners and the municipality, bears witness to a noble and fragile heritage.
