Darling's Observatory, built from 1916–17, was a private observatory built by J. H. Darling in Duluth, Minnesota. The site of the observatory was on West 3rd Sreet between 9th and 10th avenues in Duluth 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 Darling himself after inspecting domes from various other observatories. The wooden building had a stucco exterior finish. Read more on Wikipedia
