Darling's Observatory was a private observatory built by Mr. J. H. Darling in Duluth, Minnesota. The site of the observatory was on West 3rd St. between 9th and 10th avenues in Duluth, MN, and sat about 325 feet above Lake Superior (927 feet above sea level). Plans for the building were drawn by Richard E. Schmidt of Garden & Martin of Chicago. The blueprints for the steel dome were prepared by Mr. Darling himself after inspecting domes from various other observatories.
