According to Norse sagas, the city was founded by the King Harald Hardrade around 1049. There is also evidence of settlement prior to 1000 resulting in the celebration of Oslo's millennium in the year 2000. Throughout its history, the city was destroyed several times by fire, but was successfully rebuilt each time.
