Parliament Hill Fields

From the Wikipedia page on Hampstead Heath

Parliament Hill Fields lies on the south and east of the Heath; it officially became part of the Heath in 1888. It contains various sporting facilities including an athletics track, tennis courts and Parliament Hill Lido.] Parliament Hill itself is considered by some to be the focal point of the Heath, with the highest part of it known to some as "Kite Hill" due to its popularity with kite flyers.[17] The hill is 98.1 metres (322 ft) high and is notable for its excellent views of the London skyline. The skyscrapers of Canary Wharf and the City of London can be seen, along with St Paul's Cathedral and other landmarks, all in one panorama, parts of which are protected views. The main staff yards for the management of the Heath are located at Parliament Hill Fields
