A historic Toronto building is set to re-open its doors this month following years of construction, restoration, and upgrades. Known as "The Dome," the Allan Gardens Conservatory Palm House Heritage Building first opened in 1910 as the third horticultural pavilion on the site. Other renovations include the administration building, public washrooms, and park improvements. Although the Conservatory has remained open to the public, the Palm House building has been closed for a few years now, but you'll soon be able to explore it once again. According to the City's website, the Palm House building is set to re-open on May 14, 2025.
