Las Vegas said goodbye to one of their beloved hotels with a "cinematic implosion."

Around 2:30 a.m. The Riviera Casino was demolished by a massive yet fancy implosion. Fireworks were set off as the building was destroyed, making it a bittersweet moment for Las Vegas historians.

The Riviera Casino was a historic building that was acknowledged as the last relic of Vegas' Mobster past. Not only did crime get the Riviera recognized, but the hotel helped launch Vegas into a entertainment capital. It cost $42 million to implode the 13-building campus, but the history of the Riviera will live on.
