40. The Hoosier Dome
Location: 100 South Capitol Avenue, Indianapolis
Demolished: December 2008
Current status: Parking lot across the street from Lucas Oil Stadium
Famed tenants: Indianapolis Colts (NFL) (1984-2007)
The host of the Final Four in 1991 (that's the one where Duke thumped UNLV, right? It is!), 1997, 2000, and 2006, the Hoosier Dome was one of the smallest NFL venues, but Colts fans could always make up for it in volume under the 257 ton domed fiberglass and teflon roof.
