Detweiler Meetinghouse Doors Open Waterloo Region

Detweiler Meetinghouse

Ontario’s only surviving stone Mennonite meetinghouse was restored to its 1855 appearance, from its Georgian hand-blown glass windows to its original pine floors. Lively acoustics make it attractive for performances; it’s available for milestones, weddings and reunions. The adjacent historical cemetery is still in use. Stroll the grounds and enjoy this rare heritage building in its serene rural setting.
