Mind Blowing Engineering Work

ImageSapporo (A commercial city in Japan - north-western Hokkaido) stadium seating more than 42,000 people! One unique aspect of this stadium is that it is an indoor stadium with the playing field out side; however, when required, the field is moved inside the stadium. Even more dramatic is the feature that rotates the field on its axis once the field is inside. Movement of the field ensures that all the spectators get a spectacular view of the game being played!
