The 2002 park chose conversion over demolition
Seonyudo Park reused the closed waterworks and opened in April 2002. Seoul describes it as an environmental regeneration park. Regeneration differs from restoring a place to an earlier natural state. Basins, a pumping building and columns were selectively kept, while paths, plant observation, exhibitions and rest were added. Concrete and vegetation should be read as overlapping uses from two periods rather than a victory of nature over industry.
Each garden retains an earlier geometry
The Garden of Green Columns removed a filter-bed roof and retained the supports. Aquatic gardens reuse water-treatment forms, while the Garden of Time and four circular spaces adapt other structures. Poetic names can hide earlier functions, so compare past and present uses on the official map. Plants and installations are not frozen as they were in 2002. Growth, safety repairs and changing programs continue to alter the scene.
An ecological park is not unmanaged wilderness
Plants, birds and insects use the island, but planting, pruning, channel care and structural maintenance continue. Naturalized and native plants coexist; neither proves that the site represents an untouched Han River ecosystem. Seoul’s own exhibition material emphasizes coexistence between industrial traces and new ecology. Do not feed wildlife, pick plants or cross basin barriers. Urban ecology depends on visitor conduct and continuing public management.
Seonyugyo extends the park over the river
The pedestrian-only Seonyugyo links Yanghwa Han River Park to the island and turns the approach into part of the visit. It offers broad views, but photography must not block pedestrians. Repairs or weather can restrict access, so verify current notices. Entry from Yanghwa Bridge and from Seonyugyo differs in slope and experience; travelers with mobility needs should use current accessibility guidance rather than assume every historical route is suitable.
Read the sequence of reuse, not only photo spots
A short route can join the Story Hall, Green Columns, purification garden and Seonyugyo view. Exhibitions and artworks are temporary even when old photographs make them look permanent. Basin edges and stairs become slippery in rain or ice. General vehicle parking is restricted, so consult official transport information. The point is not the number of pretty gardens but how one site moved from peak to waterworks to park while selecting which earlier structures to keep.
