The recreational activity of swimming has been recorded since prehistoric times; the earliest recording of swimming dates back to Stone Age paintings from around 10000 years ago. Written references date from 2000 BC.
Swimming emerged as a competitive recreational activity in the 1830s in England. In 1828, the first indoor swimming pool, St George's Baths was opened to the public. By 1837, the National Swimming Society was holding regular swimming competitions in six artificial swimming pools, built around London. The recreational activity grew in popularity and by 1880, when the first national governing body, the Amateur Swimming Association, was formed, there were already over 300 regional clubs in operation across the country.
