Rogny-les-Sept-Écluses (French pronunciation: [ʁɔɲi le sɛt eklyz]) is a commune in the Yonne department in Bourgogne-Franche-Comté in north-central France.
The commune is located some 50 km (31 mi) west of Auxerre and is crossed by the Loing and the Briare Canal.
[3] The commune is in the natural area of Puisaye, Rogny-les-sept-écluses was simply known as Rogny before 1978, when the name was changed to mirror its famous monument.
Medals and coins bearing the image of the Emperor Constantine (306-337) and the Gaulish tyran Tetricus (268) were found along an ancient Roman road.
[6] The most remarkable possession of the church is a painting called Les Pèlerins d'Emmaüs from 1757 and designated as historical monument in 1908.
It was Hugues Cosnier's idea to build six locks (a seventh one was built later) to cross the Vallée du Loing (côte Rogny, hence the name Rogny-les-sept-écluses).
