Here's an amazing drone video of the largest hemispherical building on earth. It's called the Ericsson Globe, and it's situated in the Swedish capital city Stockholm. Sometimes simply referred to as the Globe, it's an indoor arena in the Johanneshov district of the city, the largest urban area in Scandinavia. The arena seats about 16,000 for concerts and a bit under 14,000 for hockey events. Completed in 1989, the building has an inner diameter of about 110 meters (360 ft.).
