The world's first designated

Dark Sky Island

About Sark

Sark is a small island, fourth largest of the Channel Islands, in the south-western English Channel off the coast of Normandy, France. It forms part of the Bailiwick of Guernsey and has a population of about 600.

About Us

In January 2011 Sark gained International Dark-Sky Association recognition for its exceptional quality of unpolluted darkness, and became the first functioning island community to gain the title of Dark Sky Island. It was during this time that the Sark Astronomy Society (SAstroS) was formed by a band of enthusiastic stargazers eager to share the wonders of Sark's magical night time display with others.
