THREE buildings at the heart of operations during the Second World War at RAF Northolt have been listed at Grade II by Tourism and Heritage Minister John Penrose.

The buildings comprise a C-type hangar, former Squadron Watch office, and former ‘Z’ Sector Operations Block.

The hangar was used throughout the Second World War to house Churchill’s personal aircraft in which he flew to many important meetings of the Allied leaders.

The Watch office which also served as the Aircraft Readiness room during the Second World War had an undisputed role in the Battle of Britain and was the building from which RAF Northolt’s pilots were scrambled.

The Operations Block was the prototype for the ‘Dowding System,’ a method of communication allowing the command chain to communicate to intercept enemy aircraft, the first such system in the world.

It was recently named the Sir Keith Park Building in honour of the man who developed the air defence system with Lord Dowding and then ‘fought it’ as the 11 Group commander – the busiest Group throughout the Battle.

The decision to list the buildings is on the basis of advice from English Heritage. Grade II listing means that the architectural merit of the buildings must be taken account in any future applications to develop the site.

Secretary of State for Defence, Dr Liam Fox said: “The Nation has a duty to recognise the great sacrifices made by those serving in our Armed Forces. The bravery that was displayed during the Battle of Britain continues to inspire generations of Servicemen and the Government’s decision to list these buildings will ensure the achievements of those who fought in the battle are never forgotten.”

John Penrose said: “As we celebrate the 70th anniversary of the Battle of Britain it seems entirely fitting to list these buildings which played such a pivotal role during the Second World War and beyond. Their National significance and historical importance merit the protection provided to them by listing and serve as a reminder of the great sacrifice, courage and determination showed by all those who worked at RAF Northolt during the war years.”

Station Commander Group Captain Tom Barrett said, “I am delighted that the importance of these buildings to the heritage of the Nation has been recognised. RAF Northolt is a modern and effective operational Station, but our success is built on generations of airmen and airwomen who served here before us. The decision to list Hangar 5, the Sir Keith Park Building and the Watch office ensures that they will be preserved for future generations to appreciate and understand the importance of RAF Northolt in the Battle of Britain”.
