RAF Cape D'Aguilar [????- ]
Norman Lawson was here from 15 Nov 1955 - 22 Aug 1956. He wrote that he was quartered at RAF Little Sai Wan, but "went to work at Cap [sic.] d'Aguilar, which was near a Cable and Wireless Station".
He says the Cape D'Aguilar site was a radar station, used for fighter control.
If you compare the satellite image above with this photo from Norman, the layout looks very similar:
Are some of the buildings from the 1950s still standing there?
I'd also guess that the circular platforms seen in the satellite image may have been for the radio masts shown in the photo.
