The River Culture Multimedia Museum on the Nakdong River in Daegu — a vessel-shaped pavilion clad in silver ETFE pillows, emerging from a sculpted landscape peninsula, housing immersive exhibition galleries that celebrate the relationship between nature, water, and technology.
Commissioned by Kwater Korea as part of one of South Korea’s most ambitious river restoration initiatives, The ARC was completed in 2012 on a peninsula in the Nakdong River near Daegu. The project emerged from a national effort to rehabilitate the country’s four major river systems, and it serves as both a public landmark celebrating that ecological commitment and an immersive high-tech exploration of the analog landscape.
Form & Site
The bold curved form of The ARC is perched on a peninsula that juts into the Nakdong River, surrounded by an awe-inspiring natural environment of water, mountains, and engineered topography. The building reads as a vessel emerging from the landscape — a singular sculptural gesture that serves as both landmark and threshold between the natural and the constructed. The architecture is comprised of a vessel-shaped form clad in silver-fritted ETFE pillows that, through a play of transparency and geometry, create an ephemeral effect that shifts throughout the day.
Landscape & Exhibition
The landscape design is a statement about the power and beauty of the river environment — the light and water, the mountains, the stones. The atmospheric quality of the building enclosure is heightened by the shallow reflecting pool that surrounds its base. While the visible portion of the building sits atop an artificially formed landscape berm, the exhibition galleries are concealed below grade, creating a dramatic spatial sequence as visitors descend from the entrance portal into immersive multimedia environments before ascending through blue-lit passages to the elevated viewing deck above.
Interior Passage
The interior circulation is organized as a journey from earth to sky. Visitors enter through a stone-clad portal cut into the landscape and descend to the multimedia exhibition level. From there, a compressed staircase lined in angular blue surfaces and traced by continuous LED edge-lighting creates a heightened spatial experience as visitors ascend toward the daylight visible above. The blue interior amplifies the aquatic theme while the narrow geometry intensifies the sense of emergence into the panoramic river landscape.
ETFE Envelope
The quilted cladding lining the underbelly and exterior of The ARC is an ETFE pneumatic cushion system. This facade system is lightweight, exerting minimal load on the pavilion’s steel structure, while maintaining a weathertight enclosure and providing a high-performance building skin with excellent insulation value. At night, integrated lighting transforms the ETFE surface into a luminous blue form visible across the river valley, establishing the building as a beacon within the landscape.
