Swim BIG: Artificial Island Supports World’s Largest Saltwater Pool Complex

Now open on the edge of Aarhus, Denmark’s second-largest city, the Harbor Bath project features a main 150-foot-long pool as well as diving and children’s pools, plus a pair of saunas. Naturally, the water is drawn directly in from the surroundings. Designed by architects from Bjarke Ingels Group (BIG) — images by Rasmus Hjortshøj —
