Lahti (Lahtis in Swedish) is a Finnish city of 98,413 inhabitants (2005), bordering the Vesijärvi lake. It became a city in 1905. Originally a part of Hollola, it has since grown considerably larger than its current neighbor. The symbol of the city is a burning train wheel. The terrain is unusually hilly, the city being situated on a series of ridges created in the last glacial period. Lahti is best known for its annually held World Cup winter games called "Salpausselän kisat". The city endeavours for achievements in sport, which has led to such things as the hosting of a World Games event. As of 2007, it is the only city to host the FIS Nordic World Ski Championships six times, doing so in 1926, 1938, 1958, 1978, 1989, and 2001. The city also has an Association Football (soccer) club, FC Lahti, and an ice hockey team, the Lahti Pelicans. Lahti also has perhaps the best known symphony orchestra in Finland, Sinfonia Lahti. It concentrates on Sibelius's music.
