visited today with Lesbub.
'''The Reserve Home Forces headquarters at Wentworth
The beginning of this chapter made mention of the combined services
headquarters that was to have been built in tube-type tunnels under
Whitehall. Although it was never constructed, it had a counterpart that was
indeed built, 29 miles west of London at Wentworth, Surrey.
This was the 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. The bunker
is to the south of Wentworth House (now the club house for the golf course)
and 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 directly
into the clubhouse, 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. When last opened for press inspection in
1987 the bunker was found to be in very good condition, albeit with all
suspended floors and cabling removed.'''
supposidly this was the back up D-Day control bunker network for Fort Southwick, Portsdown and HMS Forward, Newhaven.
theres also other information that was an army battle headquarters
theres no photos of this place anywhere on the internet, a few photos exist from the 1980's but thats it.
it has two main entrances, one from within the clubhouse ( which is bricked up ) and the entrance that we found open at last.. the entrance tunnels lead down to a main tunnel, down the middle are 20 rooms either side of it. the rooms are the same make and size as the deep shelters in London and seem the same size as the London Underground tunnels. the place is self is quite stripped out but is alot bigger than i thought.
if you do go or know where it is, please DEFINATELY keep access information off the internet for fear of vandalism etc and the only way in being sealed.
