Pictures: London 2012 Olympic venues
- Published

The countdown is on - it's now just one year until the London 2012 Olympics kicks off.

The Olympic site is so big you need a map to work out where all the different venues are.

Here's the aquatic centre where British Olympic stars like diver Tom Daley and swimmer Rebecca Adlington will be going for gold. The aquatic centre will use at least 10 million litres of water!

And this is where the Canoe Slalom competition will happen - at the nearby Lee Valley White Water Centre.

Most of the venues will be based in the Olympic Park in east London in and around Stratford - but some will be in other parts of London.

Footie fans will be heading a few miles across the city to where all the matches will take place - at the famous Wembley Stadium.

And this is where the beach volleyball will happen - at Horse Guards Parade near Buckingham Palace. Thousands and thousands of tonnes of sand are being brought in to create beaches for the event.

The Dome in Greenwich will host the London 2012 gymnastics events.

And Wimbledon will be where all the Olympic tennis stars will head to compete.

Back in East London, this is the velodrome where cycling stars including Sir Chris Hoy will be racing against the best cyclists in the world, hoping for another Olympic gold medal.
