Seoul Botanic Park

This guide to Seoul Botanic Park in Seoul starts with a squat wooden pumping station built in the 1920s to drain Han River floodwater off the rice paddies that once covered this plain. It follows the station through decades of use, its abandonment as Seoul grew up around it, and its recognition as the only intact pumping station from Korea's industrial past. A listening tip: look for the old pump house before circling on to the garden's glass dome.
