Erected in 1932 by winegrowers and inhabitants of the Côte des Blancs region, the Grotto of Mesnil-sur-Oger is a replica of the Grotto of Notre-Dame de Lourdes. It was blessed in 1933 by Monseigneur Tissier, bishop of Châlons en Champagne. This grotto is located near the church of Saint Nicolas, it is open to all those who would like to pray...so let us pray for the future harvest!!!!
