The Round Barn

The Mansonville Round Barn

The Mansonville Round Barn is an inspiring piece of unique architecture, and a heritage landmark that enhances the natural beauty surrounding it. The century-old barn is a priceless community asset because only seven remain in the Eastern Townships, and no other is located in a town!

At present, you can only admire the round barn from the outside, as the interior is closed for an indefinite period. Due to non-conformities, the site represents a hazard for users. The municipality is currently assessing the need for remedial work.

The park surrounding the round barn is called Place de la Grange-ronde. A preliminary development plan is available here.

The ”Action-Patrimoine” organization presented a prestigious award to the GBMP for the restoration of the Mansonville Round Barn, during an international online symposium held on October 20 and 21.
The Heritage Awards jury was particularly appreciative of the fact that the Round Barn restoration project was carried out by a group of volunteers, a project that they find inspiring for the community that advocates for heritage protection.

”Action patrimoine” is a non-profit organization, created in 1976, which acts on a national scale to protect and enhance Quebec’s heritage, both built and cultural landscapes. It publishes the excellent quarterly magazine Continuité, dedicated to heritage, and awards the Action patrimoine prizes every two years in three distinct categories. This year there were a total of 25 entries in the three award categories.

The GBMP thanks ”Action patrimoine” for the honour and recognition of its work with this prestigious award.

Future use of the round barn and the surrounding grounds

Once all the renovation works completed, the barn will become a major attraction in the Eastern Townships, complementing the new development of Owl’s Head and this will inevitably contribute to the revitalization of our village.

On the three interior levels of the barn we’ll showcase:

  • A permanent exhibition on the history and heritage of our region
  • Occasional thematic exhibitions
  • A multifunctional room for conferences, shows or receptions.

On the Barn’s grounds, you’ll continue to have:

  • An innovative and educational community garden
  • Animation for children, outdoor cinema, concerts, country parties, etc.
