Cincinnati Observatory

The Cincinnati Observatory is located in Cincinnati, Ohio on top of Hyde Park. It consists of two observatory buildings housing an 11 inch and 16 inch aperture refracting telescope. It is the oldest professional observatory in the United States. It was a key facility for astronomical research and education at the University of Cincinnati and currently operates as a 19th-century observatory. There are regular viewings through both historical telescopes as well as tours and additional programs. The observatory also has an extensive outreach program, providing astronomical education for the Ohio/Kentucky/Indiana region.
Cincinnati Observatory was built by Ormsby M. Mitchel at the peak of Mount Ida, a hill that overlooks downtown Cincinnati. Nicholas Longworth donated 4 acres of land for the purpose. The Holy Cross Monastery and Chapel stands today at the site. The cornerstone was laid on November 9, 1843, and presiding over the occasion was former President John Quincy Adams, with an introduction by Judge Jacob Burnet. At 77 years old, it was to be his last public speech, and Mount Ida was renamed to Mount Adams in his honor.
