The Observatory’s Warner & Swasey 9-inch refracting telescope, which looks like something out of a Jules Verne novel, offers students incredible views of the moon, the spot on Jupiter, and the rings of Saturn.

More about Swasey Observatory

In 1909, Denison University Trustee Ambrose Swasey contributed the funding to build an observatory, which he also furnished with its original astronomical equipment. At that time, his firm, the Warner & Swasey Co. of Cleveland, had manufactured many of the world's finest and largest telescopes. Built of white Vermont marble, the interior was renovated and the outer dome replaced in 1970.
