Dollis Hill is an area of north-west London. It lies close to Willesden, in the London Borough of Brent. As a result, Dollis Hill is sometimes referred as being part of Willesden, especially by the national press. Dollis Hill consists of the streets surrounding Gladstone Park, formerly the estate belonging to Dollis Hill House.
The Dollis Hill Estate was formed in the early 19th century, when the Finch family bought up a number of farms in the area to form a single estate. Dollis Hill House itself was built in the 1820s.
The first railway in the area was the Dudding Hill Line, opened in 1875 by the Midland Railway to connect its Midland Main Line and Cricklewood goods yard in the east to other lines to the south-west. The Dudden Hill station on the line closed for passengers in 1902, but the line still carried freight.
The code-breaking Colossus computer, used at Bletchley Park during the Second World War, was built at the Post Office Research Station in Dollis Hill by a team led by Tommy Flowers. The station was relocated to Martlesham Heath at the end of the 1970s. The Post Office Research Station building has now been converted into 62 flats and is now known as 'Chartwell Court', with an access road called 'Flowers Close'.
Famous residents 
William Ewart Gladstone, the UK Prime Minister, was a frequent visitor to Dollis Hill House in the late 19th century. The year after his death, 1899, Willesden Council acquired much of the Dollis Hill Estate for use as a public park, which was named Gladstone Park.
Eric Simms, the ornithologist, broadcaster and author, lived in Brook Road. His book, Birds of Town and Suburb (1975), was based on his studies of the birds in Dollis Hill.
