A swimming pool,
swimming bath, wading pool, paddling pool, or simply a pool, is a man-made
container filled with water intended for swimming or other water-based recreation.
A pool can be built either above or in-ground, and be constructed from
materials such as concrete (also known as gunite), metal, plastic or
fiberglass. Pools can be decorative or custom shape and size, or they may be
standard sizes, the largest of which is the Olympic-size swimming pool.

Many health clubs
such as the YMCA, fitness centers and private clubs have public pools used
mostly for exercise. Many hotels have pools available for their guests.
Educational facilities such as schools and universities occasionally have pools
for swimming or physical education classes, or competitive athletics such as
swim team. Hot tubs and spas are pools with hot water, used for relaxation or
therapy, and are common in homes, hotels, clubs and massage parlors. Swimming
pools are also used for diving and other water sports, as well as for the
training of lifeguards and astronauts.
History
The "Great
Bath" at the site of Mohenjo-Daro in modern-day Pakistan was most likely
the first swimming pool, dug during the 3rd millennium BC. This pool is 12 by 7
metres (39 by 23 feet), is lined with bricks and was covered with a tar-based
sealant.

Ancient Greeks
and Romans built artificial pools for athletic training in the palaestras, for
nautical games and for military exercises. Roman emperors had private swimming
pools in which fish were also kept, hence one of the Latin words for a pool,
piscina. The first heated swimming pool was built by Gaius Maecenas of Rome in
the first century BC. Gaius Maecenas was a rich Roman lord and considered one of
the first patrons of arts.
Ancient Sinhalese
built pairs of pools called "Kuttam Pokuna" in the kingdom of
Anuradhapura, Sri Lanka in the 4th century BC. They were decorated with flights
of steps, punkalas or pots of abundance and scroll design.
Modern pools
Swimming pools
became popular in Britain in the mid-19th century. As early as 1837, six indoor
pools with diving boards existed in London, England. The Maidstone Swimming
Club in Maidstone, Kent, England is believed to be the oldest surviving
swimming club in Britain. It was formed in 1844, in response to concerns over
drownings in the River Medway, especially since would-be rescuers would often
drown because they themselves could not swim to safety. The club used to swim
in the River Medway, and would hold races, diving competitions and water polo
matches. The South East Gazette July 1844 reported an aquatic breakfast party:
coffee and biscuits were served on a floating raft in the river. The coffee was
kept hot over a fire; club members had to tread water and drink coffee at the
same time. The last swimmers managed to overturn the raft, to the amusement of
150 spectators.
In 1839, Oxford
created its first major public indoor pool at Temple Cowley, and swimming began
to increase in popularity. The Amateur Swimming Association was founded in 1869
in England, and the Oxford Swimming Club in 1909 with its home at Temple Cowley
Pool.
The presence of
indoor baths in the cobbled area of Merton Street, London may have persuaded
the less hardy of the aquatic brigade to join. So, bathers gradually became
swimmers, and bathing pools became swimming pools.
The modern
Olympic Games started in 1896 and included swimming races, after which the
popularity of swimming pools began to spread. In the USA, the Racquet Club of
Philadelphia clubhouse (1907) boasts one of the world's first modern
above-ground swimming pools. The first swimming pool to go to sea on an ocean
liner was installed on the White Star Line's Adriatic in 1907. The oldest known
public swimming pool in America, Underwood Pool, is located in Belmont,
Massachusetts.

Interest in competitive
swimming grew following World War I. Standards improved and training became
essential. Home swimming pools became popular in the United States after World
War II and the publicity given to swimming sports by Hollywood films like
Esther Williams' Million Dollar Mermaid made a home pool a desirable status
symbol. More than fifty years later, the home or residential swimming pool is a
common sight. Some small nations enjoy a thriving swimming pool industry (e.g.
New Zealand pop. 4,116,900 [Source NZ Census 7 March 2006] - holds the record
in pools per capita with 65,000 home swimming pools and 125,000 spa pools).
