The Howard Peters Rawlings Conservatory and Botanic Gardens of Baltimore, often known as the Baltimore Conservatory, is a historic conservatory and botanical garden located in Druid Hill Park at 3100 Swann Drive, Baltimore, Maryland. The conservatory is open daily except Mondays and Tuesdays. Designed by George A. Frederick (architect of Baltimore City Hall), the conservatory opened to the public on August 26, 1888, with a major renovation circa 2002-2004 that added two new pavilions. It now contains five distinct areas: the 1888 Palm House, the Orchid Room, Mediterranean House, Tropical House, and Desert House. Conservatory grounds (1½ acres) feature 35 flowerbeds.
