Seonyudo Park

Seoul, South Korea


The site, which covers over 100,000 square metres, incorporates industrial landmarks and infrastructure from the treatment plant into its design. It contains four ecological zones and seven key facilities.

Zone 1: Water purification

The first zone converts the former water purification basin into a series of pools. Natural, organic processes are now used to clean the water. Each basin contains different plant species that can be seen from low-lying walkways, allowing children and adults to enjoy the plant life in close proximity.

The water from the basins is channeled to the Ecological Water Playground - a gently sloping collection of spiral mounds and shallow water pools where children can play and parents can cool down on a hot day.

Zone 2: Garden of Green Columns

The ‘Garden of Green Columns’ contains rows of ivy-clad columns, formerly the main reservoir’s foundations.

Zone 3: Aquatic Botanical Garden

Shallow filtration basins, previously used to remove debris from the water, have become an ‘Aquatic Botanical Garden’. This contains a variety of native Korean plant species. A hothouse at its eastern end houses tropical and subtropical aquatic plants and exotic evergreen shrubs.

Zone 4: Garden of Transition

The ‘Garden of Transition’, another former chemical settlement facility, houses an aroma garden, a vine garden, a moss garden and a fern garden.

The four zones are connected with other public facilities by a maze of paths, boardwalks and elevated walkways that run alongside a network of pipelines and water conduits. These include:

  • a 200-seat open-air amphitheatre
  • an exhibition hall with a permanent exhibition about the Han River
  • a traditional Korean pavilion looking out across the river’s northern banks
  • a café built on the site of the former pumping station
  • an observation deck.

The island is accessible from the motorway, by water taxi and the Seongyugyo pedestrian bridge.
