The River Westbourne which flowed through the park was dammed to form a lake. The east and west halves of the lake, known as the Serpentine and the Long Water are divided by a bridge designed by George Rennie in 1826. It has a magnificent prospect. Hyde Park has been open to the public since 1635 and demonstrates the value of a really large boldly planted park in a city. It is enlivened by two fine modern restaurants, one at each end of the Serpentine. Apart from this feature, so appropriately named for an example of the Serpentine Style, the park has never been designed as a whole. Visitors to London can contrast its style with the Baroque style of the adjoining Kensington Gardens.
