The Mansonville round barn, located in the heart of the village, is a heritage jewel. It piques the curiosity of visitors because there are only seven of them left in the Eastern Townships, all built between 1901 and 1915. After more than a year of renovations, the round barn is now reopened to the public every Saturday in the summer. Not only will you have the opportunity to admire its unique architecture, but you will also be able to see exhibitions that will be presented there. Outside, on the Grange-Ronde square, visitors can also visit the public market that is held every Saturday from 9 a.m. to 1 p.m.
