Hyde Park. Hyde Park is a Grade I-listed major park in Central London. It is the largest of four Royal Parks that form a chain from the entrance of Kensington Palace through Kensington Gardens and Hyde Park, via Hyde Park Corner and Green Park past the main entrance to Buckingham Palace. The park is divided by the Serpentine and the Long Water lakes. The park was established by Henry VIII in 1536 when he took the land from Westminster Abbey and used it as a hunting ground. It opened to the public in 1637 and quickly became popular, particularly for May Day parades. Major improvements occurred in the early 18th century under the direction of Queen Caroline. Several duels took place in Hyde Park during this time, often involving members of the nobility. The Great Exhibition of 1851 was held in the park, for which The Crystal Palace, designed by Joseph Paxton, was erected. Free speech and demonstrations have been a key feature of Hyde Park since the 19th century. Speakers' Corner has been established as a point of free speech and debate since 1872, while the Chartists, the Reform League, the suffragettes, and the Stop the War Coalition have all held protests there. In the late 20th century, the park was known for holding large-scale free rock music concerts, featuring groups such as Pink Floyd, The Rolling Stones and Queen. Major events in the park have continued into the 21st century, such as Live 8 in 2005, and the annual Hyde Park Winter Wonderland from 2007. Hyde Park is the largest Royal Park in London. It is bounded on the north by Bayswater Road, to the east by Park Lane, and to the south by Knightsbridge. Further north is Paddington, further east is Mayfair and further south is Belgravia. To the southeast, outside the park, is Hyde Park Corner, beyond which is Green Park, St. James's Park and Buckingham Palace Gardens. The park has been Grade I listed on the Register of Historic Parks and Gardens since 1987. To the west, Hyde Park merges with Kensington Gardens. The dividing line runs approximately between Alexandra Gate to Victoria Gate via West Carriage Drive and the Serpentine Bridge. The Serpentine is to the south of the park area. Kensington Gardens has been separate from Hyde Park since 1728, when Queen Caroline divided them. Hyde Park covers 142 hectares, and Kensington Gardens covers 111 hectares, giving a total area of 253 hectares. During daylight, the two parks merge seamlessly into each other, but Kensington Gardens closes at dusk, and Hyde Park remains open throughout the year from 5 a.m. until midnight. The park's name comes from the Manor of Hyde, which was the northeast sub-division of the manor of Eia and appears as such in the Domesday Book. The name is believed to be of Saxon origin, and means a unit of land, the hide, that was appropriate for the support of a single family and dependents. Through the Middle Ages, it was property of Westminster Abbey, and the woods in the manor were used both for firewood and shelter for game. Hyde Park was created for hunting by Henry Vlll in 1536 after he acquired the manor of Hyde from the Abbey. It was enclosed as a deer park and remained a private hunting ground until James I permitted limited access to gentlefolk, appointing a ranger to take charge. Charles I created the Ring, and in 1637 he opened the park to the general public. It quickly became a popular gathering place, particularly for May Day celebrations. At the start of the English Civil War in 1642, a series of fortifications were built along the east side of the park, including forts at what is now Marble Arch, Mount Street and Hyde Park Corner. The latter included a strongpoint where visitors to London could be checked and vetted. In 1652, during the Interregnum, Parliament ordered the then 620-acre park to be sold for ready money. It realised E17,000 with an additional E765 6s 2d for the resident deer. During the Great Plague of London in 1665, Hyde Park was used as a military camp. Following the Restoration of the Monarchy in 1660, Charles II retook ownership of Hyde Park and enclosed it in a brick wall. He restocked deer in what is now Buck Hill in Kensington Gardens. The May Day parade continued to be a popular event; Samuel Pepys took part in the park's celebrations in 1663 while attempting to gain the King's favour. In 1689, William III moved his residence to Kensington Palace on the far side of Hyde Park and had a drive laid out across its southern edge which was known as the King's Private Road.
