Called a "sacred place of healing and hope" by President Barack Obama, the official dedication ceremony took place for the 9/11 museum on Thursday May 15th. It was a long, hard road to get to this point from the day that tragedy struck and changed everyone's lives.     A webcam was set up shortly after the 9/11 attacks that captured the entire process of rebuilding the site and the 9/11 museum. The time-lapse video footage is nothing short of stunning. The webcam and all its footage have been donated to the 9/11 Memorial Museum.
