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.
