Bournemouth (/ˈbɔːrnməθ/ BORN-məth) is a coastal resort town in the Bournemouth, Christchurch and Poole unitary authority area, in the ceremonial county of Dorset, on the south coast of England. At the 2021 census, the built-up area had a population of 196,455, making it the largest town in Dorset.
Previously an uninhabited heathland, visited only by fishermen and occasional smugglers, a health resort was founded in the area by Lewis Tregonwell in 1810. After the Ringwood, Christchurch and Bournemouth Railway opened in 1870, Bournemouth grew into an important resort town, which today attracts over five million visitors annually for its coastline and nightlife.
