The Transformation of Seonyubong
The history of Seonyudo is one of dramatic physical change. Originally, the area was a small mountain known as Seonyubong. During the Japanese colonial era, the mountain was significantly altered as rocks were harvested to pave roads and construct flood control measures.
The landscape changed permanently during the construction of the Yanghwa Bridge, which took place between June 1962 and January 1965. This massive infrastructure project resulted in the complete disappearance of the original Seonyubong mountain, leaving behind the island we recognize today.
From Water Filtration to Public Green Space
For over two decades, from 1978 to 2000, Seonyudo served a vital industrial purpose as a water filtration plant, providing essential tap water to the southwestern districts of Seoul. Following the plant's closure in December 2000, the site underwent a massive revitalization project.
Instead of erasing the industrial past, the city chose to repurpose the existing structures. On April 26, 2002, the site officially opened to the public as Seonyudo Park, an ecological park designed to harmonize man-made elements with nature.
Exploring the Park's Composition
Seonyudo Park is divided into several specialized areas that highlight its unique history and ecological mission:
Han River Exhibit Hall
This hall serves as an educational center, featuring various photos and videos that document the history and the changing four seasons of the Han River.
Water Purification Plant and Playground
In a clever display of sustainability, the park features a functional water purification system made by recycling the former filtration plant. This system uses aquatic plants—plants that grow in or on water—to naturally purify water, which is then used to supply various park facilities. This purified water also feeds the water playground, a safe area for children featuring shallow water (approximately 15 cm deep).
Garden of Green Column
One of the most striking visual features of the park is the Garden of Green Column. This area preserves the concrete columns that once served as vestiges of the reservoir used to hold water. Today, these columns are covered in climbing ivy, creating a beautiful intersection of industrial ruins and lush greenery.
