When the Olympics come to your city, you can bet a shiny new stadium will be coming your way. Or at least, an old stadium will be getting a new roof.

With the Summer Olympics coming to Rio de Janeiro soon, now seemed like the perfect time to look back at the world's remaining Olympic stadiums. Some show off fascinating displays of architecture, while others are just plain huge.

Here are 16 of the coolest looking Olympic stadiums around the world.

The Bird's Nest, used during the 2008 Beijing Olympics, is an architectural marvel. Artist Ai Weiwei, who's become internationally famous for his criticism of the Chinese government, served as a consultant on the project.

The Chinese National Aquatics Center hosted swimmers during the 2008 Olympics and will be used for curling events during the 2022 Winter Olympics.

The Iceberg Skating Palace in Sochi, Russia hosted figure skating and speed skating during the 2014 Winter Olympics. It fits right into its icy surroundings.
