The Allegheny Observatory is an American astronomical research institution part of the Department of Physics and Astronomy at the University of Pittsburgh. The observatory was founded on February 15, 1859 by the Allegheny Telescope Association.
A model of the original observatory can be found in the Miniature Railroad & Village exhibit at Carnegie Science Center in Pittsburgh and in 2012 a documentary film was released covering the observatory's history.
The observatory consists of a library, lecture hall, classrooms, laboratories, offices, and three hemispherical domed telescope enclosures. The core of the building is a small rotunda, housing an opalescent glass window depicting the Urania, the Greek muse of astronomy.
The Allegheny Observatory was re-designed in 1900 with the public in mind. Astronomer John Brashear once said "the Allegheny Observatory would remain forever free to the people," and the observatory continues to offer free public tours from April through October.
