On the 16th, the city announced that it had signed a business agreement with Innoun Group at the Daseulbang in City Hall for the construction of the 'Siheung Aquarium (tentative name)' and has begun moving forward with the project as of June 17, 2026.

This agreement was reached after a public competition and the selection of a preferred negotiation partner, following a memorandum of understanding (MOU) signed with Innoun Group in April last year. Through this process, the city plans to accelerate the revitalization of tourism on Turtle Island and the expansion of marine leisure tourism infrastructure.

The Siheung Aquarium will be built on a site of approximately 7,000 square meters within Neighborhood Park No. 50 in Siheung MTV, consisting of one basement level and three above-ground floors. The total tank volume is planned to reach 11,000 tons, making it the largest aquarium in Korea upon completion. The target opening year is 2029.

Currently, Korea Water Resources Corporation is constructing an underground parking lot with a capacity for 1,000 vehicles at the project site. In the future, the site will be developed into a complex tourism space that combines the upper neighborhood park and the aquarium. The city expects to invest more than 200 billion won in the related projects.

In particular, the city plans to connect a variety of tourism infrastructure, including a Ferris wheel and marine leisure facilities, centered around the aquarium, with the aim of transforming Turtle Island into a leading marine tourism destination in the metropolitan area.

Kim Seungmin, CEO of Innoun Group and Animal Kingdom Co., Ltd., stated, "The Siheung Aquarium will feature an animal welfare-oriented design with natural light on every floor, international-scale exhibition spaces, and innovative exhibition techniques. We plan to introduce an immersive ecological aquarium where animals live naturally and visitors can enter and experience their world."

Siheung Mayor Lim Byeong-taek said, "With the signing of this business agreement, we will proceed smoothly with the necessary administrative procedures to ensure that Turtle Island grows into an integrated tourism hub that combines marine leisure, tourism, and culture. We will also further strengthen our efforts to expand tourism infrastructure, revitalize the local economy, and enhance urban competitiveness."

Meanwhile, Siheung City is preparing to become the leading marine leisure tourism city in the metropolitan area by gradually implementing tourism infrastructure projects, including the Siheung Aquarium, a Ferris wheel, and marine leisure facilities.
