The Athletes' Village was converted into a suburb called Newington, featuring eco-friendly residential apartments, with solar power and a recycled water supply. Most of the sporting facilities still get quite a bit of use: the aquatics center hosts swimming competitions, and is also open to the public for recreational activities, with a water slide, spa and fitness center. The 690 million Australian dollar main stadium still hosts major sporting events, including cricket and rugby, despite its capacity being scaled down from 110,000 to 83,000
In Nagano, five large structures were built for the 1998 Winter Games. They remain in use, though many complain that the venues are too big and costly to maintain for a town of less than 400,000 people.
The Olympic Stadium has been converted into a baseball stadium. Nagano doesn't have a professional team, though other teams play there on occasion.
The Aqua Wing Arena has been converted into an aquatics center, and the Big Hat is still used for ice hockey, as well as figure skating. The M-Wave hosted the World Sprint speed-skating championships last month, and the White Ring is used for professional basketball, volleyball and other events.
Nagano wasn't free from controversy, though. The bidding process for the games was clouded by bribery allegations.
In Atlanta, the main stadium for the 1996 summer Olympics is headed for demolition.
After the 1996 games, the stadium was converted into Turner Field, the baseball stadium that's been home to the Atlanta Braves for the past several years. But in November, the team announced plans to build a new stadium in the city's northwest suburbs and leave Turner Field in 2017. Atlanta Mayor Kasim Reed said that Turner Field would be demolished after their departure.
Less than two miles north of the stadium, in the city's downtown area, Centennial Olympic Park was used for some of the ceremonies during the Atlanta games. The park remains a popular destination for residents and tourists, particularly in the warmer months. Every summer, children still splash in a large fountain that incorporates the Olympic rings in its design.
