Phipps Conservatory.

Set in Schenley Park, Phipps Conservatory and Botanical Gardens is a striking blend of Gilded Age history and cutting-edge ecological design. At its heart is the original 1893 Victorian glasshouse, a 14-room steel-and-glass masterpiece designed by Lord & Burnham. Inside, the conservatory pioneered the art of themed, narrative-driven floral displays, which still rotate seasonally alongside permanent collections of orchids, bonsai, and desert plants. Across its 15 acres, the experience shifts from historic formal gardens to the soaring Tropical Forest Conservatory. What truly sets Phipps apart, however, is its reputation as one of the world's greenest public gardens; the campus features some of the globe's most sustainable architecture, making a visit here as much about the future of green design as it is about historic horticulture.
