The Pontiac Silverdome is a vacant sports stadium which was formerly the home of the Detroit Lions football team and the Detroit Pistons basketball team. Other major events occurred in the stadium, including Wrestlemania III, which set a world record for attendance at an indoor event. The Silverdome has been vacant since 2012, and the contents are to be auctioned off. This video shows the current dilapidated state of the Silverdome. Credit: YouTube/ Detroiturbex.com
