The Conservatory began as a community effort in 1914 to provide a place to house exotic plants that residents collected during their travels abroad. The present Edwardian-style glass structure, built in 1929, houses a botanical collection of more than 3,000 plants, some of which date back to the Conservatory's founding.
Over the years the building fell into neglect. In 1970, when plans were made to raze it, a group of concerned citizens led a successful drive to preserve, and eventually enhance, this unique resource. In June of 2000 the Conservatory Center was opened to provide expanded space and facilities for educational programming, day-to-day operations and public events. http://www.pdop.org/parks/pf_18.htm
