Dear All,
I know very little about WWII in Malta, or how to reply on this forum for that matter, but have just been on a course staying near Dingli and thought I would pass some info on for what it is worth. The course was held at Villa Psaigon near Dingli (google maps: Psaigon, Triq IL-Buskett, Dingli, Malta) not far from and within sight of the radar station at Dingli cliffs. It is now primarily used as a youth centre. The caretaker of the building told us that it had been used by the British during the war, I think he said for intercepting German messages. The building is a very solid square fortress-like building with an inner courtyard and thick walls, it has two floors. The front entrance has big wooden coachhouse-like doors with a small door in the main door that you can climb through to enter without opening the big doors. The doors are protected with metal barred gates in front. The main room which we used had a heavy steel safe-like door. The door at the rear of the building was I think also steel, secured by pulling across heavy bolts. The caretaker told us that (in true Maltese style) there was a functioning water reservoir under the courtyard. He was very surprised that he had not found the old air-raid shelters, which he was convinced must be there somewhere. I hope this information be of some help.
