Was talking about Drumskinny stone circle with a friend yesterday which led to doing a little online research - it seems that it has recently been restored. My friend had visited forty years ago as a newly-wed with his young wife. He had just found a note written by her listing the wild flowers they found there - which were Ladysmock, Crossleafheath, Common Milkwort, Bog Cotton, and Ragged Robin. The restoration photographs show lots of gravel making it look less natural/wild and more sterile.
Would love to locate some old photos but can't find any online. Am hoping there are some somewhere - or hear from anyone who remembers it as it was before restoration.
