Good post!
As usual Louis's posts sends me on a research adventure....
Although aware of the war Rooms I had no idea how extensive they were and that there is a group actually restoring them.
Now another place on my list of Would Like to Go To's.
"Located 150 feet under the Upper Barracca Gardens and the Saluting Battery in Valletta, the Lascaris War Rooms represent one of Malta’s best kept secrets from World War Two.
This ultra secret complex housed an operations room for each of the fighting services which included the hugely important RAF Sector Fighter Control Room from where all air and sea operations were observed and controlled. This was supported by a Filter Room through which all radar traffic was channelled and sifted and an Anti-aircraft Gun Operations Room from where artillery fire against air attack was coordinated. A Combined Operations room served for joint operations, within a heavily guarded facility which accommodated the encryption machines used to receive and send secret communications. Being so deep underground the whole complex was mechanically ventilated – one of the original features that still works.
In July 1943, the War Rooms were used by General Eisenhower and his Supreme Commanders Admiral Cunningham, Field Marshal Montgomery and Air Marshal Tedder as their advance Allied HQ for Operation Husky – the Invasion of Sicily.
Following the end of the war, it became the Mediterranean Fleet HQ. In 1967 it was taken over by Nato to be used as a strategic Communication Centre for the interception of Soviet submarines in the Mediterranean. It remained in that role for the next ten years when it was finally closed down. The War Rooms played an active part in the Anglo-French invasion of Egypt during the Suez Crisis in 1956 and went into full alert for a number of days during the Cuban Missile Crisis of 1962 when a Soviet missile strike against Malta was expected.
In 2009, Fondazzjoni Wirt Artna – the Malta Heritage Trust has embarked on the restoration of this historic complex. Since, then its volunteers have spent many selfless hours in painstakingly getting it back to its former glory."
