Château de Beauregard

Château de Beauregard is a medieval fortress located in Publy in the Jura region at roughly 660 meters elevation. The remains include a square keep with a corbelled turret that commands views across the surrounding landscape.

The fortress was built in the 10th century for the Coligny lords and stood at the crossing of two major trade routes. King Louis XIV ordered its destruction in 1668, leaving only these remains today.

The northeast wall of the keep shows three decorative windows and a preserved arrow slit that reveal medieval defense techniques. These architectural details tell the story of how such structures were built and protected against attack.

Access to the ruins requires driving from Lons-Le-Saunier along the D52 toward Montaigu, then the D52A to Nogna, followed by an uphill walk. The final climb is steep, so wear suitable footwear and allow time for the elevation gain.

The name comes from the sweeping views across the villages of Marnézia, Dompierre-sur-Mont, Nogna, and Saint Maur that open up from the site. This vantage point was equally valuable for those who once held and defended the fortress.
