It is where General Eisenhower and Field Marshal Montgomery, together with Admiral Ramsay – commander of the Allied Naval Expeditionary Force – planned operations Overlord and Neptune.
The date for D-Day was set there 75 years ago.
It is now used by the Defence School of Policing and Guarding, but still has the map room inside.
The D-Day landings onto the beaches in Normandy were originally scheduled for the 5th June 1944 – but in true British fashion, the weather had other ideas.
Although US meteorologists believed conditions would be suitable, British scientist James Stagg thought otherwise.
He managed to convince commanders to delay the operation by 24 hours, and hold out for better weather – it was the right call.
With the 75th anniversary of that day approaching – many will return to Normandy in June to remember the realities of the events that were planned at Southwick House.
