United States Botanic Garden Conservatory

The Conservatory building of the United States Botanic Garden on the National Mall was completed in 1933 and houses a living collection of plants representing a range of global habitats. The institution traces institutional roots to federal botanical collections established in the early 19th century and is one of the nation's oldest public botanic gardens. The glasshouse architecture of the Conservatory is designed for public display, education, and plant conservation programs.
