You learn something new every day. "A north Belfast mountain's connection to World War Two can still be seen today by the presence of a white stone. A local postman was commissioned by the Ministry of Defence in 1941 to paint a large stone on the mountain white. The stone, on Cave Hill, was used to help guide allied pilots into wartime airfields in Belfast at the time. In recent times, a plaque on the mountain to mark the war effort has been defaced." www.bbc.co.uk/news/av/uk-northern-ireland-61396942?fbclid=IwAR0QEW5nor4VxQIi7m2whdIe9eBhVA3XCmdt_rmkRczW_lCzOH0Tp10hPko
