18. The Astrodome, Houston, Texas
The Astrodome in Houston, Texas, was the first of its kind when it opened in 1965. Home to baseball’s Houston Astros and the NFL’s Houston Oilers, the dome once also reverberated with the sounds of rodeos, Elvis Presley gigs and a Muhammad Ali bout. But by 2000 the Oilers and Titans had moved out and in 2008 it was closed by the Fire Department. The venue last made headlines when it provided shelter for people evacuated from New Orleans following 2005’s Hurricane Katrina.
17. The Pontiac Silverdome, Pontiac, Michigan
For a quarter of a century, the 80,000-capacity Pontiac Silverdome was the pride of Detroit. And during that time it hosted the likes of the 1982 Super Bowl, 1994 FIFA World Cup matches and Michael Jackson and Rolling Stones gigs. However, after being abandoned by the Detroit Lions in 2002, it fell into decline. Then, in 2013, bad weather brought its once state-of-the-art inflatable roof crashing down, giving it a seriously post-apocalyptic makeover.
16. Olympic Village, Athens, Greece
Although it’s famous for its ancient monuments, Greece now has some more recent ruins. And thanks to the 2004 Olympic Games, they include the Olympic Village in Athens. What’s more, it was hoped the Games would be a money fountain for the country. However, sunseekers instead headed to Italy in 2004 in order to avoid the crowds caused by the event.
