Ynys Enlli, otherwise known as Bardsey Island, is a tiny remote Welsh island located two miles off the tip of the Llŷn Peninsula in north Wales. With a population of just four people, no electric grid, cars or indoor toilets, Ynys Enlli has now achieved an even more remarkable feat: becoming the first site in Europe to be awarded International Dark Sky Sanctuary (IDSS) certification.
The trust which owns Ynys Enlli said gaining such ‘prestigious status’ was a ‘huge achievement’. The island’s mountain acts like a barrier to limit light from the mainland, which means the most significant light pollution comes from Dublin, over 70 miles (112.6 km) across the Irish Sea.
The International Dark Sky Places certification process is similar to other conservation and environmental designation programs, such as the UNESCO World Heritage Sites. There are several different categories, including dark sky parks, communities, reserves, sanctuaries, and urban night sky places. Each category has its own set of guidelines based on land management, size, and sky quality. Dark sky sanctuaries have to be public or private land, accessible to the public in part or whole, and must provide an exceptional view where the night sky brightness is routinely equal to or darker than 21.5 magnitudes per square arc second.
Sian Stacey, chair of the Bardsey Island Trust said: ‘There’s no doubt that achieving this prestigious status for Ynys Enlli will raise the profile of the island as a unique place in Wales and amongst the best in the world to appreciate the night sky.’
The tiny community is accessible only by boat from a small fishing village on the mainland, but centuries ago, the scrap of land was one of the most significant religious sites in Britain. Mari Huws is one of the Wardens
