Dave Shilabeer has sent the Gurn some pictures and he tells us:
"We had a gentleman come into the museum a few weeks ago asking about holes in the rocks between the Golf View and the swimming pool. I had to put my hands up and say I didn't know. Walking along the prom this morning I noticed them properly for the first time so am asking your readers help. This section I have photographed is right under the wall of the prom and there is a line of 7 holes running parallel to the wall about 2 metres (6ft) away. There are others in the area but I can't make out a discernible pattern. The holes are about 8cm (3in) in diameter. "
