The air defence of Britain was run from a country house in Stanmore
A Soane villa on the hill above the Broadway became the headquarters of RAF Fighter Command, and stayed in uniform for eighty-two years.
Every town on our books has a big house on a hill. Very few of them have one where the whole country's fighter defence was directed for the duration of a war, and fewer still where you can now park a coach outside the door and walk in.
A house, then an air force
Bentley Priory was designed by Sir John Soane in 1775 for James Duberley, and significantly extended by Soane again in 1788 for John Hamilton, first Marquess of Abercorn. Robert Smirke added to it in the early 1860s. It is listed Grade II*, and for most of its first century and a half it was exactly what it looks like: a large private house with a view south over Middlesex.
The Air Ministry bought it in 1926. Ten years later, on 14 July 1936, the Royal Air Force reorganised itself into functional commands and RAF Fighter Command was formed, with its headquarters here. Its first Air Officer Commanding-in-Chief was Air Chief Marshal Sir Hugh Dowding, who held the post from that day until 25 November 1940 — through the whole of the thing he is remembered for.
What was actually decided here
Fighter Command was not a squadron. It was a structure, and Bentley Priory sat at the top of it. Beneath the headquarters were the regional Groups: 11 Group covering south-east England and London, 12 Group the Midlands and East Anglia, 13 Group the north of England and Scotland. 10 Group was added for south-west England in June 1940 and 14 Group for the far north on 26 June 1940, as the fighting spread. Two more Groups did the unglamorous work that made the rest possible: 60 Group ran the Chain Home radar stations, and 30 Group the barrage balloons.
That is the part worth pausing on. Radar was not a gadget bolted onto the RAF; it was wired into a chain of command that ran from a coastal aerial through a Group headquarters to this house on a hill in Stanmore and back out to an aerodrome, fast enough to matter. The Battle of Britain, officially 10 July to 31 October 1940, was fought by roughly 1,963 RAF aircraft against about 2,550 German ones. The arithmetic was not in Britain's favour. The organisation was.
Dowding's name went onto the building in the end. In 1943 he was raised to the peerage as Baron Dowding of Bentley Priory — a title taken not from a family seat but from an office.
Eighty-two years in uniform
The RAF stayed. Fighter Command's war ended, the Cold War came and went, and Bentley Priory remained in service in one role or another until 2008, closing finally on 30 May that year. In 2011 the estate was bought by City & Country with Barratt Homes, and the historic core was kept back from the housing.
The Bentley Priory Museum was formally opened in September 2013 by Charles III, then Prince of Wales, and opened fully to the public in January 2014. It is run by the Bentley Priory Battle of Britain Trust, and the grounds around it are now a nature reserve.
Why a minibus firm goes on about it
Because it is the one address in Stanmore that publishes the rules for arriving as a group, and then keeps to them. Three coach bays. Drop-off at the door. Pre-book over twenty. Over thirty and you are coming on a Tuesday or a Thursday, whatever the coach costs.
A house built for one family in 1775, requisitioned to command an air force in 1936, and now open on a timetable that depends on how many of you there are. It is worth the trip, and it is worth the phone call first.
Tell us the group size before you tell us the date, and for this one venue we will tell you which days are even possible.
