A Red Brick Angled Wall atop a hillside South of Victoria Island.
This is an incredible long-shot, but as the years go on, it is one of the last gaps of knowledge about my Hong Kong. Which was the period 1955-1957. When the Royal Navy Hong Kong Flotilla with it's heavily armed wooden Motor Launches patrolled "South" , I remember looking high up, from the sea below, near Stanley, and seeing a red-brick built angled wall, with a large open cement like shute/drain down to the sea. In the folk-lore of the times, and as a teenager sailor, I was told that it was a wall against which the Japanese executed persons during the occupation by firing squad.
