Beijing Olympic venues - Bird's Nest, Ice Ribbon and bullet trains

The Beijing Winter Olympics will be spread over three zones and merge new venues with existing ones from the 2008 Games, including the "Bird's Nest" stadium.

With one month to go, AFP Sport looks at where the Olympics will take place:

Beijing

The 80,000-seater "Bird's Nest" National Stadium -- whose cross-hatched steel girders produce a nest-like appearance -- will stage the opening and closing ceremonies.

Other sites from the 2008 Games have also been spruced up. The "Water Cube" aquatics centre has been restyled as an "Ice Cube" for curling.

The Wukesong Sports Centre and fan-shaped National Indoor Stadium -- which held the basketball and gymnastics events in 2008 -- have been renovated to host ice hockey.

The only new addition to Beijing's existing Olympic Park is a 12,000-capacity speed skating oval nicknamed the "Ice Ribbon".

New venues have been built in other parts of the city, such as the striking location for some of the freestyle skiing and snowboarding events.

The 60-meter-high "Big Air" jumping platform stands in the shadow of four vast cooling towers at a former steel mill that once employed tens of thousands of workers and is now a trendy bar, restaurant and office complex.

Yanqing

The Beijing Olympics has prompted a government-backed winter sports drive that aims to build a one-trillion-yuan ($156 billion) industry by 2025.

The Olympic zone of Yanqing -- a suburb about 75 kilometers (50 miles) northwest of the city centre -- is already home to several ski resorts and swanky hotels.

It's also the site of China's first bobsleigh, skeleton and luge tracks at the National Sliding Center, which can seat 2,000 people and accommodate a further 8,000 standing spectators.

Nearby is a new 8,500-capacity centre for alpine skiing, with vertical drops reaching up to 900 meters (3,000 feet).

Zhangjiakou

China has linked the small city of Zhangjiakou -- about 180 kilometers northwest of Beijing -- to the other two Olympic hubs via what state media claims is the first rail line allowing driverless trains to reach speeds of up to 350 kilometers per hour.

The popular resort area has also added an unconventional ski-jumping venue designed to resemble a traditional "ruyi" scepter symbolizing power and good fortune.

Organizers have temporarily taken charge of an existing resort to hold some of the freestyle skiing and snowboarding competitions.

It lies a few kilometers from Zhangjiakou hub's Olympic Village, a cluster of chalet-style apartments ringed by mountains.

There are three newly constructed villages -- one in each of the three hubs -- to accommodate over 6,000 athletes and officials in total.

They will be converted into public housing or business parks after the Games.
