Great place to see Seoul's growth and history at a glance
The museum's long shape represents the waterways of the Cheonggyecheon Stream. The permanent exhibition hall displays the history of Cheonggyecheon in miniature, as well as its current and future appearance through media, as well as a glimpse into Seoul's past and the lives of its citizens over time. The special exhibition hall is packed with exhibitions from various fields that the museum has organized, so there is plenty to see. Afterward, visitors can relax in the cozy rooftop garden, which provides panoramic views of Seoul, or visit the 1st-floor library to learn about history.
