Clarke Observatory

The Clarke Observatory is located on the Mount Union College campus in Alliance, Ohio.

History

Originally built for private use, the observatory was sold to Elmer Harrold, another private owner, who donated to Mount Union College upon the graduation of his daughter from the college. A new observatory was built on campus to house the observatory in 1923 and outfitted with the telescope from the first Clarke Observatory. The second observatory was demolished in 1969 and the telescope moved to a new home attached to East Hall at Mount Union College.
