A Starlight Reserve is a site where a commitment to defend the night sky quality and access to starlight has been established. Its main function will be to preserve the quality of the night sky and its associated values — be they cultural, scientific, astronomical, natural, or landscape-related.

The concept of a Starlight Reserve goes further than the mere protection of the site's astronomical integrity. It aims to recover and identify existing values related to the night sky, encompassing landscape, nature, opportunities for science, astrotourism and, in general, the vast arena of cultural heritage — tangible and intangible.
