Constructed by POSCO E&C, the Tri-Bowl is a complex cultural space aimed at promoting local culture and allowing citizens to enjoy culture, serving as a landmark located in Songdo Central Park at the center of Songdo International City, Incheon.
As the world's first reverse shell structure, the Tri-Bowl is a masterpiece that simultaneously realizes architectural technology and artistic symbolism through its globally pioneering reverse shell design. By featuring a design where three bowl shapes—symbolizing the three core districts of the Incheon Free Economic Zone (Songdo, Cheongna, and Yeongjong)—float toward the sky, it embeds the values of balanced regional development and connection within the space. Spanning a 12,300 m² site with 1 underground floor to 3 ground floors and a total floor area of 2,700 m², the Tri-Bowl received high praise for both its formative beauty and structural difficulty, winning the Grand Prize at the 2010 Good Design (GD) Awards and elevating the status of Korean architecture. Currently, the Tri-Bowl is utilized as a complex cultural space hosting various cultural programs such as performances, exhibitions, and citizen events, establishing itself as a cultural hub and landmark of Songdo International City. Through architectures like this that enhance city value and add culture to citizens' lives, POSCO E&C continues to create richer spaces and more moving cities.
