Designed by internationally acclaimed architect Zaha Hadid, the breathtaking Aquatics Centre is one of the permanent venues specially constructed for London 2012.
Tickets are not required for some parts of the 10km Marathon Swimming, so spectators will be able to watch for free. As it's an outdoor event, spectators are advised to come prepared for all types of weather conditions.
The Swimming pool for the London 1908 Olympic Games was built on the infield of the Athletics track at White City Stadium, and the competition was held outdoors.
The first official tie for a gold medal in Olympic Swimming history came in Los Angeles 1984, when American teammates Nancy Hogshead and Carrie Steinseifer swam identical times in the 100m Freestyle.
Johnny Weissmuller, the first man to swim 100m in under a minute, was just as famous out of the pool: he played the role of Tarzan 12 times on the silver screen.
The crawl technique used in freestyle was developed by a British swimming instructor named J Arthur Trudgeon, who based it on a Native American style of swimming that he had discovered during a trip to South America in the 1870s.
Underwater Swimming featured at the Paris 1900 Games. Competitors earned points for the length of time and distance they were underwater.
