Botanical Garden

This guide to Copenhagen's Botanical Garden opens with giant bamboo that once grew fast enough to punch through the greenhouse's glass roof in a single day. It traces the Palm House itself back to 1874, when Carlsberg founder J. C. Jacobsen modeled it on London's Crystal Palace, and to the palms and cycads inside that are older than the building around them. Climb the cast-iron spiral staircase for the view down onto leaves planted before the dome went up.
