Pénitencier de Prony, Prison ruins in Mont Dore, New Caledonia.
Pénitencier de Prony is a former penal settlement with stone walls and metal structures standing among forest vegetation near Baie de Prony. A stream runs through the site, flowing past the scattered remnants of colonial-era buildings.
The penal settlement was established in 1867 when Captain Sebert arrived with 29 convicts to start a timber operation for the French colony. The site grew out of France's need for resources and labor in its overseas territories.
For people in New Caledonia, this place marks a period of French colonial expansion and forced labor systems. The ruins tell the story of how convicts were sent to work in remote locations far from home.
Access to the ruins is via the GR1 walking trail that connects from Baie de la Somme, allowing you to explore the site on foot. The terrain is wooded and can be muddy, so proper footwear and rain gear are advisable.
The buildings blend French colonial design with local materials like timber and stone, creating structures distinct from typical European architecture. This mix shows how the convicts and colonists improvised with what was available, adapting to the challenging island environment.
