Haas–Lilienthal House (Victorian house museum)

The Haas–Lilienthal House, built in 1886, is one of the few intact Victorian family houses in San Francisco open to the public as a house museum. The Queen Anne–style residence preserves original architectural details, period interiors, and family collections that illustrate late-19th-century domestic life in the city. It is designated as a San Francisco Landmark and is operated by a nonprofit organization offering guided tours and educational programs.
