Inside Golden Gate Park’s Commission Vault Museum, a steel room preserving 130 years of park history

A museum built into a former cash vault

A new micro-museum inside Golden Gate Park is turning a long-used administrative space into a public-facing archive of San Francisco’s park system. The Commission Vault Museum occupies a steel vault at McLaren Lodge, the San Francisco Recreation and Park Department’s headquarters at the eastern edge of the park. The building, completed in 1896 as the residence and workplace of park superintendent John McLaren, remains a central hub for park administration today.

The museum’s footprint is unusually small: a roughly 6-by-10-foot room with a capacity of about five visitors at a time. The space was originally designed for secure storage, including concession cash receipts, and has been repurposed into a compact exhibit gallery that requires reservations and coordination with adjacent meeting-room availability.

How the collection surfaced and what it contains

The exhibit developed from historical materials that had been stored for decades in filing cabinets, drawers and boxes associated with the Recreation and Park Commission’s records. The project began as an effort to digitize documents and preserve fragile paper items. During that work, staff identified materials that warranted public display, including late-19th-century event advertisements and other ephemera tied to park life.

The display was assembled by Recreation and Park Commission liaison Ashley Summers and department historian-in-residence Christopher Pollock. The project budget was kept below $10,000, relying on in-house city labor for installation work and outside construction for display cases.

• Approximately 125 objects and images presented as a decade-by-decade timeline
• Tickets, brochures and postcards tied to public programming and recreation
• Historic sports photographs, including games played at Kezar Stadium and Candlestick Park
• Selected artifacts such as an early Playground Commission-era sign and historic photographs, including imagery from around 1900

A timeline that tracks the city’s park buildout

Organized by decade, the exhibit’s timeline begins in the mid-19th century and charts the growth of the park system. It includes park counts at the close of each decade, documenting an expansion from 14 parks in 1860 to 230 parks by 2025. The exhibit also highlights the administrative evolution that shaped recreation and open space in San Francisco, including early playground governance and the later consolidation of city recreation and park oversight into today’s structure.

Access, limitations, and near-term facility needs

The museum had a quiet opening in December 2025 and has operated without standard public hours, reflecting both the room’s small capacity and the logistical constraints of entering through a working government facility. In the same period, the McLaren Lodge meeting room used to access the vault was identified for repairs related to water damage, underscoring the challenges of maintaining historic civic buildings while expanding public access to collections housed inside them.

In a city where parks function as everyday infrastructure, the museum is designed to preserve the administrative and cultural record of how those spaces were built, used and governed over time.
