Here, on the occasion of the Journées du Patrimoine (Heritage Days), a host of visits and events await you!
Heritage Days at Saint-Mammès church
Guided tour of Saint-Mammès church
The village church, dedicated to Mammès, a saintly healer from Cappadocia, was probably built around the year 1000, in the pre-Romanesque style.
It houses a 13th-century statue of the saint, a beautiful 14th-century statue of the Virgin and Child, and several 13th-century tombstones.
Heritage Days at Saint-Mammès lock
The Saint-Mammès lock is an exception on the Canal du Loing. While the majority of locks are perré, the Saint-Mammès lock is bajoyers.
Discreet and intact, the lock keeper's house is, with a few modifications, exactly as it was designed in the 18th century. Its distinctive feature is a slate roof, in a region where tiles are the predominant roofing material.
Heritage Days at the Place de la Bosse in Saint-Mammès
At the confluence of the Seine and Loing rivers, Saint-Mammès will take you back in time to the history of inland waterway transport, which still gives rhythm to the life of this picturesque village.
