The Infinite Bridge in Aarhus, Denmark
A bridge comes full circle
If residents of Aarhus, Denmark's second-largest city, feel like they're going around in circles, then it might have something to do with this wooden walkway. The Infinite Bridge, or 'Den Uendelige Bro' to locals, is about 200 feet in diameter. It forms a perfect circle overlapping the sand and sea, offering sweeping views across Aarhus Bay and along the tree-lined beach. Designed by Danish architects Niels Povlsgaard and Johan Gjødes, it was originally constructed as a temporary display in 2015 for the city's Sculpture by the Sea exhibition. But the never-ending pier proved so popular, the city now opens the bridge to circular meandering each spring and summer.
