Atlanta (CNN)The only facility in the world to host the Olympics, Super Bowl and Final Four has been reduced to rubble. A little more than 25 years after opening, the Georgia Dome, former home of the Atlanta Falcons and the scene for several historic sporting events, was imploded Monday morning. The adjacent Mercedes-Benz Stadium opened this summer. The blast occurred just after 7:30 a.m. ET. Most of the structure collapsed, though parts of it remained upright.
