The Conservatory of Flowers is a greenhouse and botanical garden that houses a collection of rare and exotic plants in Golden Gate Park, San Francisco, California. With construction completed in 1878, it remains the oldest building in the park, and the oldest municipal wooden conservatory remaining in the United States. It is also one of the first municipal conservatories constructed in the country. For these distinctions and for its associated historical, architectural, and engineering merits, the Conservatory of Flowers is listed on the National Register of Historic Places, the California Register of Historical Places, is a California Historical Landmark, and a San Francisco Designated Landmark.
