4. The Ericsson Globe

Year Opened: 1989

Location: Stockholm, Sweden

The dome has been a popular ice hockey arena design since Mellon Arena in Pittsburgh opened in 1958, but the Swedes went one better and constructed The Ericsson Globe. The Globe is biggest hemispherical building in the world with a diameter of 361 feet and is Sweden’s national indoor arena. It closely resembles an oversized ping pong ball but also represents the Sun in the Sweden Solar System, the largest scale model of our Solar System in the world. In 2010, a funicular was added along the outer of the globe to give tourists an unparalleled view of Stockholm.
