Lady Gaga has upload  to her YouTube account, the time lapse footage of the 2012-2013 Born This Way Ball world tour stage, the largest escenic structure ever been built to tour. The stage and set had many capabilities and functions, including 30 active windows and doors, each with a custom scenic painted roll drop which revealed different scenes within the various rooms of the castle, two swing walls which opened to reveal the 50 foot tall castle behind it, 620 feet of custom LED lights and two sets of automated castle gates that opened and closed to a full 180 degrees.
It took fifteen 53 foot long tractor trailers to move the castle and the main stage, and there are approximately 200 set carts that all of the elements travel in. To put that in perspective, if all of the set carts were lined up end to end, they would span approximately 1600 feet in length, the equivalent of over 5 football fields.
