The world's biggest chess game

The Kyffhäuser-Denkmal (Kyffhäuser Monument) is also known as the Barbarossa-Denkmal (Barbarossa Monument) or the Kaiser-Wilhelm-Denkmal (Kaiser Wilhelm Monument) and stands on the summit of the Kyffhäuser Mountain at an elevation of over 1,574 feet (500 metres), near Bad Frankenhausen in the state of Thuringia in central Germany. The monument itself is 265 feet (80 metres) tall and was built at the end of the 19th Century in 1890-96 and features a 22 foot (6.5 metres) tall sandstone figure of the medieval Holy Roman Emperor Frederick I von Hohenstaufen, better known as Barbarossa, with a bronze equestrian statue of Kaiser William I above him. The tower itself is topped by a huge imperial crown, which can be reached by visitors by climbing a 247-step stairway. From there you have an excellent panoramic view of the surrounding countryside.

There is a tradition of building giant field images in front of the Kyffhäuser Monument, to attract even more tourists. This year the image was of a truly gigantic chess board measuring 400 x 400 metres (1200 x 1200 feet) on its side. It was built on a harvested field in full view of the monument.

Since August 17, 2009, Germany's strongest female player, IM Elisabeth Pähtz, is playing a game on this giant chessboard. Her opponents are a virtual chess community voting for their moves on the Internet. This can be done up to 10:00 a.m. every day. Elisabeth then has time until 4 p.m. to play her move. With each move the pieces are adjusted on the chessboard. You can watch the game on a web cam here:
