The Hermitage of Saint-Rouin is a modern chapel built on the site of an ancient hermitage where Saint-Rouin, founder of the Beaulieu-en-Argonne abbey, lived in the 7th century. The chapel, designed by the architect and Dominican friar L.-B. Rayssiguier, is a striking example of concrete architecture with geometric shapes and colorful stained glass windows. You can admire the minimalist interior and the altar made of sandstone blocks, as well as the 17th century altarpiece of the Assumption located in the enclosure. The Hermitage of Saint-Rouin is a place of pilgrimage and celebration every year on September 17, the feast day of Saint-Rouin. You can also enjoy the natural beauty of the surrounding forest and the panoramic views from the hilltop. The Hermitage of Saint-Rouin is a hidden gem that will inspire you with its history and art.
