Built on a Davis Mountains peak with money left by a Texas banker who had never shown any interest in astronomy, and who left his fortune to a university he had no connection to. It has some of the darkest skies in the continental United States, and nearby towns write lighting rules to keep them.
That was 1 of the hidden places.
