Not a huge amount is known about the whole history of this bunker what is known is that this was a D-Day control bunker, unusual both on account of its tube
construction and its location in a private estate between Sunningdale and
Virginia Water, close to the world-famous golf course.
The estate was commandeered on the outbreak of World War II and
became a military encampment. Files in the Public Records Office indicate
the bunker was constructed in anticipation of a devastating bombardment and
resulting evacuation of London and its layout is identical to that proposed
initially for the combined services deep bunker under Whitehall. It consists of twin segmental cast iron tubes, evidently taken from London
Transport stock, about 100 yards long, separated by a smaller diameter
access tunnel. The latter connects via ramps and stairs at one end, and at the other to an isolated escape exit. The whole
is protected on the surface by a massive bombproof slab with a brick
ventilation cowl protruding. The slab is now used as a car park.
Wentworth had been earmarked by General Sir Alanbrooke, Commander in
Chief Home Forces, as his HQ in the event of an invasion that never in fact
came and in due course Wentworth was used as a signals centre by the 21st
Army Group in the lead up to D-Day.
