The Stellafane Observatory is an astronomical observatory in Springfield, Vermont, founded in 1920 by Russell W. Porter. The Pink Clubhouse was built in 1923 at the site by the Springfield Telescope Makers Club. The name Stellafane, suggested by Porter at the club's December 1923 meeting, is derived from the Latin words stella and fanum meaning "Shrine to the Stars", and originally referred specifically to the clubhouse, but has since come to refer to all of the club's land and buildings on the summit of Breezy Hill, west of downtown Springfield.
