The Original Governor’s Mansion will temporarily close to public tours beginning November 1, 2025, as contractors begin a series of critical exterior repairs aimed at preserving one of Montana’s most cherished historic landmarks.
The restoration effort, funded through the Governor’s Long-Range Building Program, will address both the mansion and its adjacent historic carriage house. Planned improvements include repairing and repainting the upper balustrade, main-level deck, and front porch—work that state officials say is essential to maintain the structural integrity and safety of the century-old property.
“While previous maintenance has been performed over the years as funding allowed, the exterior of these buildings has experienced significant wear,” said 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 Helena businessman William Chessman, the ornate Queen Anne-style residence once stood as a testament to the city’s prosperity during Montana’s early years of statehood. The state purchased the home in 1913, and for nearly 50 years it served as the official residence of nine Montana governors and their families.
After the construction of the current Governor’s Residence in 1959, the mansion was converted into a museum managed by the Montana Historical Society. Today, it serves as both a cultural landmark and educational site, drawing thousands of visitors each year with its rich collection of period furnishings and stories from Montana’s political past.
During the renovation, the mansion will be closed to all tours and public programs. The Montana Historical Society expects the work to continue through the winter months, with a reopening planned for spring 2026, depending on weather and construction schedules.
Officials encouraged the public to stay updated through the Historical Society’s website and social media for announcements on progress and reopening dates.
“This project is about stewardship,” Bramble said. “We’re ensuring that future generations can continue to walk through these rooms and connect with the people and stories that shaped Montana’s history.”
