The park was created by transforming the Sinwol Water Purification Plant, which operated from 1959 until 2003.
The 'Airy Fountain' operates via a sound-sensor system that detects the noise of approaching aircraft to launch water jets.
The park covers approximately 220,000 square meters of reclaimed industrial land.
Original water pipes and concrete filtration basins were preserved and integrated into the landscape design as art installations.
The central lake is frequently used for migratory bird spotting during spring and autumn.
Seoseoul Lake Park occupies the site of a former water purification plant, retaining repurposed industrial infrastructure within a landscaped public space. The park features a central 20,000-square-meter lake as its primary hydrological feature. A signature 'Airy Fountain' system uses sensors to trigger water jets when airplanes fly overhead, referencing the park's proximity to Gimpo International Airport. The grounds include expansive walking paths, wildflower gardens, and designated picnicking zones. It is situated in the Yangcheon District, serving as a repurposed urban ecological zone. The design incorporates remnants of the old filtration tanks and steel structures, blending industrial history with recreational green space.

Bring a portable mat for picnicking, as grass areas are popular but seating is limited.
Visit the 'Airy Fountain' area on the side facing the flight path to see the water jets activate.
Follow the perimeter trails to view the repurposed industrial sculptures integrated into the natural scenery.
Do not attempt to swim in the lake, as it is a preserved ecological water feature, not a recreational pool.
Maintain noise levels near residential sections; keep pets on a leash and clean up waste.
