The tower's architecture was specifically designed to camouflage a large-scale municipal waste incineration plant located entirely underground.
The stack uses advanced filtration technology to ensure the emissions dispersed at the height of the tower meet strict environmental standards.
The Hanam Waste Resource Center operates as a landmark model for underground municipal utility integration in dense urban environments.
The observation deck features transparent glass floor sections for visitors to view the ground directly beneath their feet.
Union Tower is a 105-meter-tall observatory tower located within the Hanam Environmental Foundation facility in Gyeonggi-do, South Korea. The structure serves as the exhaust stack for the underground Hanam Waste Resource Center, utilizing a tall chimney design to disperse emissions while providing public observation space. Visitors access the observation deck via a glass-walled elevator that offers an external view of the surrounding complex. The 360-degree observation deck provides views across the Han River, the Paldang Reservoir, and the mountainous topography of the Gyeonggi province. The base of the tower is integrated into a multi-purpose cultural and sports park, including aquatic centers and recreational grounds.

Visit the integrated park at the tower's base to explore the extensive walking trails and sports facilities after viewing the observatory.
Check the horizon for visibility conditions before traveling, as smog or mist can significantly obscure the mountain views.
Visiting on days with high fine dust warnings, as the visibility from the tower will be severely limited.
Closed on Mondays and major public holidays; check for temporary closures due to facility maintenance.
