The route of Blackbird Hill has been in existence since the Domesday Book.

No addresses have so far been added to Blackbird Hill, NW9

In 1597 many roads converged on Kingsbury Green. One, originally called Ox Street or London Lane and later Kingsbury Road, ran eastward to the Hyde; Buck Lane, earlier known as Stonepits or Postle Lane, ran northward from Kingsbury Green to join Hay Lane, a road mentioned in the 13th century. Another early road in northern Kingsbury was Tunworth or Stag Lane, which ran from Redhill to Roe Green. Church Lane, in 1563 called Northland Lane, ran southward from Kingsbury Green to the church and Green Lane joined the green to Townsend Lane, known as North Dean Lane in 1394 and 1503. On the west Gibbs or Piggs Lane joined Kingsbury Green to Slough Lane or Sloe Street, as it was called in 1428. The southward extension of Slough Lane, Salmon Street, was called Dorman Stone Lane in the 15th and 16th centuries. There was an east-west road joining Hill and Freren farms to Hendon. The portion between Church Lane and Salmon Street, called Freren Lane in 1379, had disappeared by the early 18th century. That between Townsend Lane and Hendon, known as Wadlifs Lane in 1574, survives as Wood Lane.

The portion of road between the Brent and the junction of Salmon Street and Forty Lane, now called Blackbird Hill, was usually known as Kingsbury Lane.

From ancient times the river Brent had probably been crossed at Blackbird Hill, the point where Salmon Street crosses the river. The road and bridge were mentioned in 1531 and in 1596 there was said to have been a footbridge there from time immemorial. Responsibility for its repair was divided between the lords of Kingsbury and Neasden manors. There was a ford next to the bridge for horses and carts, except when the river was in flood when the footbridge might be used by horses. Jon Chalkhill’s water-mill of 1596 caused the formation of a large pool which submerged the ford. All Souls College built a bridge strong enough to take horses and carts and agreed with Chalkhill that he would repair it as long as he retained his mill.

Responsibility probably reverted to the college during the 17th century, and in 1824 Kingsbury vestry asked it to repair or rebuild the bridge. It is not known whether the bridge was repaired then but in 1826 it was described as wooden and 11 ft. wide, spanning a river 33 ft. wide and 6 ft. deep.

In 1921, the disused pleasure grounds at Wembley Park were chosen as the site for the British Empire Exhibition.

This opened at Wembley Park in 1924. A new bridge was built in 1922 as part of the changes connected with the Exhibition.

Kingsbury Lane was soon widened, and its steep gradient up from the river evened out, to become a modern highway with a tarmac surface. Church Lane was also widened, with a new section built (Tudor Gardens) to provide a better connection to Forty Lane, and cut out the winding narrow stretch which ended at Blackbird Farm. Forty Lane and Kenton Lane were widened and straightened. These improved road connections, as well as the publicity about the area resulting from the Exhibition, attracted the attention of property developers.

The widening of Forty Lane and Blackbird Hill opened up the whole of southern Kingsbury to the builders and roads and houses to the east of Salmon Street, between Queens Walk and Old Church Lane, were constructed during the early 1920s. During that period industry was established in Edgware Road and at Kingsbury Works in Kingsbury Road, and 37 council houses were built at High Meadow Crescent near Kingsbury Green.

In 1926 work began on a new north-south road to follow the route of the ancient Honeypot Lane. By 1935 Kingsbury had been covered by a network of suburban roads, although most of the old roads survived.

In the late 1930’s the brewers, Truman Hanbury Buxton, submitted plans to build a public house on the site of Blackbird Farm. The recently formed Wembley History Society was among the objectors wishing to see the farmhouse retained and reused. The farmhouse was demolished in 1955, with “The Blackbirds” public house built around 1957.

“The Blackbirds” proved to be a popular pub with both local people and with visitors coming to Wembley for football matches. However, by the time the old Wembley Stadium closed in 2000, other leisure activities meant that the traditional English public house was going out of fashion. A “re-branding” in the mid-2000’s as an Irish-themed pub, the “Blarney Stone”, kept the hostelry on Blackbird Hill in business for a few more years, but by 2010 a planning application was submitted to redevelop the site for a block of flats.

Planning permission for the proposed development was given by Brent Council in March 2011, but one of the conditions for this was that there should be a proper archaeological excavation of the part of the Blackbird Farm site which had not been disturbed when the pub was built. The “Blarney Stone” has since been demolished.

Post by John Dye: Cool Oak Lane, NW9

I lived at Queensbury Road, Kingsbury during World War II and used to play regularly along the edge of the Welsh Harp. About halfway along Cool Oak Lane on the south side was a pond we used to call Froggy Pond. It was the only place I ever saw a water scorpion, Nepa cinerea. At the end of the war, all the street air raid shelters were knocked down and the rubble was piled up on the ground south of the Cool Oak Lane bridge, on the Hendon side. I remember that this heap of rubble became infested with rats and I used to watch them from the bridge. I was told that an old house on the south side of Cool Oak Lane (Woodfield House?) was once owned by the wife of Horatio Nelson. I think it later became the nurseries for plants grown for the Hendon parks.

Kingsbury

Kingsbury station was opened on 10 December 1932 as part of the Stanmore branch of the Metropolitan Railway and served by that company’s electric trains.

After the formation of London Transport in 1933 this branch became part of the Metropolitan line and was later transferred to the Bakerloo line in 1939 then to the Jubilee line in 1979. The design style is similar to that of other Metropolitan Railway buildings of the same period rather than to the concrete and glass style used at the same time by the LER group.

In common with other nearby Metropolitan Railway stations (e.g. Harrow-on-the-Hill, Neasden, Queensbury) there is an element of fiction in the station name; the area is properly within the eastern extent of Kenton (Kingsbury Road at this point was originally part of the eastern end of Kenton Lane) and Kingsbury proper is actually closer to Neasden station.

Although now only served by deep-level tube trains, the section of line serving the station is built to surface gauge, and trains to that larger LU loading gauge occasionally pass through.

John Rocque Map of Wembley, Kingsbury, Willesden and Harlesden (1762)
John Rocque (c. 1709–1762) was a surveyor, cartographer, engraver, map-seller and the son of Huguenot émigrés. Roque is now mainly remembered for his maps of London. This map dates from the second edition produced in 1762. London and his other maps brought him an appointment as cartographer to the Prince of Wales in 1751. His widow continued the business after his death. The map covers an area from Harrow in the northwest to Harlesden in the southeast.
