Carrières de Confrécourt, Former limestone quarry in Berny-Rivière, France

Carrières de Confrécourt is a group of four underground limestone quarries near Vic-sur-Aisne, on the commune of Nouvron-Vingré. The quarries were worked from the Middle Ages using the "piliers tournés" technique, leaving broad chambers with rough-hewn walls and ceilings. The visitable quarry, about 150 metres long, has a main entrance and a smaller second entrance, with a chapel carved at the far end.

The quarries were worked for building stone since the Middle Ages, likely opened to rebuild the farm at the end of the 14th century during the Hundred Years' War. From late September 1914 French units sheltered in them, a few hundred metres behind the front, until March 1917; they returned in 1918. The farm above was totally destroyed.

Soldiers left over sixty carvings in the quarries, including regimental badges at the main entrance and a chapel dedicated to Father Doncœur with the inscription "Dieu protège la France". The altar as it stood in December 1914 appears in Louis Tinayre's painting "La messe de minuit à Confrécourt", bought in 2019 for the Soissons museum.

Visiting requires advance reservation arranged through local heritage organizations, with guided tours available on specific days throughout the year. Comfortable shoes are recommended due to uneven underground surfaces and varying floor conditions in the chamber network.

The First Zouaves military unit created a decorated entrance portal displaying their regiment's emblem, which leads into the tunnel network below. This artistic marking demonstrates how soldiers maintained their military identity even in underground spaces.
