Opened in 1908, Garfield Park Conservatory is one of the largest conservatories in the nation, occupying two acres of public greenhouse space and 10 acres of outdoor gardens on a beautiful site designed by William LeBaron Jenney. The conservatory is known as “landscape art under glass,” and one visit to environments like the Palm House, Fern Room, Desert House, and Aroid House will tell you why. You’ll also find waterfalls, koi ponds, turtles, and birds as you wander the conservatory’s lush expanses. Garfield Park Conservatory, 300 N. Central Park Ave. free admission.

Best Large City in the U.S.

Chicago Botanic Garden

Harold Washington Library winter garden

Harold Washington Library Center

Quiet contemplation reigns within Harold Washington Library’s winter garden. There really is no better place to lose yourself in the pages of a good book. The garden’s glass-roofed atrium offers natural, filtered light year-round, ensuring leafy plants and trees thrive and blossom. While you’re there, take in the building’s exterior architecture, too — particularly the roof. Four 12-foot barn owls grace the roof’s corners, accompanied by 75-foot-wide and 40-foot-high swirls of leaves and seed pods, representing growth and wisdom. A 3-ton great horned owl, with 20-foot wingspan, sits above the main entrance on State Street. It clutches an open book, ready to take flight — in other words, always return your books! Winter Garden at Harold Washington Library, 400 S. State St., Loop, free admission.
