The gardens were founded in 1893 by steel and real-estate magnate Henry Phipps as a gift to the City of Pittsburgh. Its purpose is to educate and entertain the people of Pittsburgh with formal gardens (Roman, English, etc.) and various species of exotic plants (palm trees, succulents, bonsai, orchids, etc.). Currently, the facilities house elaborate gardens within the fourteen room conservatory itself and on the adjoining grounds. In addition to its primary flora exhibits, the sophisticated glass and metalwork of the Lord & Burnham conservatory offers an interesting example of Victorian greenhouse architecture.
