The St. Vrain Historical Society, Inc. (SVHS) is a 501(c)(3) non-profit organization based in Longmont, Colorado, dedicated to preserving the history and heritage of Longmont and the surrounding St. Vrain Valley. The Society’s mission is to “assure a future for our community’s past,” fostering an appreciation of local history and enhancing community engagement. SVHS works to achieve this through historic education, interpretive programming, and the preservation of four key historic sites: Historic Hoverhome, the Hover Farmstead, Old Mill Park, and "Old" St. Stephen’s Church.
SVHS is managed by a board of directors, who meet monthly, and is supported by one full-time staff member, a part-time staff member, and hundreds of active volunteers. Additionally, SVHS offers numerous committees that allow members to get involved in areas of personal interest.
As a long-standing advocate for historic preservation, SVHS has played a key role in shaping local preservation policies, including the designation of historical properties in three downtown districts. At Hoverhome, Old Mill Park, "Old" St. Stephen’s Church, and the Hover Farmstead, SVHS has earned a strong reputation for successfully completing preservation projects, maintaining historic properties, and ensuring they are accessible to the public.
SVHS membership is open to anyone with an interest in historic preservation or local history. The Society’s members, ranging from long-time residents to newcomers of all ages, share a common dedication to preserving the area’s heritage. This commitment is demonstrated through countless hours of volunteer service to the Society.

The Affolter Cabin at Old Mill Park recently underwent an important preservation project to protect and maintain this historic structure. This project phase, successfully completed in the Spring of 2025, involved replacing the sill course logs on the east (living quarters) side of the cabin, which had suffered damage due to log rot and age. Log repair efforts included the replacement or restoration of one log on the east elevation, five logs on the north elevation, and one log on the west-facing elevation of the east cabin, at sill level and above. These repairs were carefully executed to match the existing log dimensions, wood species, and traditional joinery styles.
The project was spearheaded by The St. Vrain Historical Society, Inc., a local nonprofit dedicated to preserving the history of Longmont and the St. Vrain Valley.
Funding for this project was made possible through the sponsorship of the Longs Peak DAR Chapter and the National Society Daughters of the American Revolution. The St. Vrain Historical Society also wishes to acknowledge the many generous donations from community members and donors who supported this project with their contributions.
We are also grateful to Deep Roots Craftsmen for their essential support and expertise throughout this successful project.
While this phase marks a major milestone, our preservation efforts of the Affolter Cabin are far from complete. Preservation is an ongoing effort, and we still need the support of our community to continue this work. Approximately four more phases are needed to ensure the cabin's lasting preservation.
