The Serpentine

The Serpentine is a 40-acre recreational lake in Hyde Park, London, England, created in 1730 at the behest of Queen Caroline. Although it is common to refer to the entire body of water as the Serpentine, strictly the name refers only to the eastern half of the lake. Serpentine Bridge, which marks the boundary between Hyde Park and Kensington Gardens, also marks the Serpentine's western boundary; the long and narrow western half of the lake is known as the Long Water. The Serpentine takes its name from its snakelike, curving shape, although it only has one bend.

Originally fed by the River Westbourne and Tyburn Brook in the 1730s, the lake's water was then pumped from the Thames in the 1830s. The water is now pumped from three boreholes within Hyde Park, the most recent being installed in May 2012 as part of the 2011–2012 restoration of the Lake.
