Historic Governor’s Mansion to Undergo Essential Restoration
Helena, MT — The Original Governor’s Mansion will temporarily close to public tours beginning on November 1, 2025, as contractors undertake critical exterior repairs to the building.
The restoration project, funded through the Governor’s Long-Range Building Program, will address both the mansion and its historic carriage house. Planned improvements include repairing and repainting the upper balustrade, main level deck, and front porch—essential work to ensure the structural integrity and safety of the site.
“While previous maintenance has been performed over the years as funding allowed, the exterior of these buildings has experienced significant wear,” explained Darby Bramble, Education Officer with the Montana Historical Society. “This comprehensive restoration will replace deteriorating exterior components, apply fresh protective coatings, and safeguard the mansion’s future as a symbol of Montana governance.”
Built in 1888 by William Chessman, the opulent Queen Anne-style residence and its two-story brick carriage house represent an important chapter in Montana’s history. The state acquired the property in 1913, and for nearly five decades, the 21-room mansion served as home to nine Montana governors and their families. For many decades since, it has welcomed thousands of visitors as a historic museum under the management of the Montana Historical Society.
Trick-Or-Treat Event Before Closure
Before the temporary closure begins, the Montana Historical Society invites the community to enjoy a special Halloween trick-or-treat event on Friday, October 31, from 5:00 to 7:00 P.M. Visitors are encouraged to come in costume to view intricately carved pumpkins, explore the festively decorated carriage house, and collect treats while experiencing the mansion’s historic charm.
During the Halloween event, street access to the Original Governor’s Mansion will be from 6th Avenue.
Tours will resume later this year upon completion of the restoration work. For updates on reopening dates and ongoing programs, please visit mths.mt.gov or contact Darby Bramble at
