The Louvre Museum in Paris is a former palace of 243,000 sqm. The exhibition halls occupy (only them) 73,000 sqm, the equivalent of ten football stadiums. There are some 14.5 km of corridors to explore it. 403 pieces. 10,000 steps. 73 elevators. 2,000 doors. Enough to give work to 2,500 employees and 10 million visitors! (Video is made by World Walkerz)
