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.
Campaigners are appealing for members of the public to treat it and the surrounding mountain with respect.
