Dollis Hill is an area in north-west London, which consists of the streets surrounding the 35 hectares (86 acres) Gladstone Park. It is served by a London Underground station, Dollis Hill, on the Jubilee line, providing good links to central London. It is in the London Borough of Brent, close to Willesden Green.
The area is mainly residential (Edwardian terraced and 1920s/30s semi-detached houses) with a restaurant, greengrocer and convenience stores near the underground station.
Dollis Hill played a part in the Second World War as the code-breaking computer used at Bletchley Park was built at the Post Office Research Station in Dollis Hill and the rarely used alternative Cabinet War Room bunker for Winston Churchill's government was dug underground here.
