International Dark Sky City

On October 24th, 2001, the City of Flagstaff became the World’s First
“International Dark Sky City.”

The designation was awarded by the International Dark-Sky Association (IDA), a tax-exempt non-profit organization dedicated to preserving and protecting the nighttime environment and the heritage of dark skies. The International Dark-Sky City designation is given to identify towns and cities “with exceptional commitment to and success in implementing the ideals of dark sky preservation and/or restoration, and their promotion through quality outdoor lighting.”
