Join us for a guided tour of the historic Frankel Detroit Observatory, the second-oldest building on campus and a center for discovery since opening in 1854. Hear stories about the people who shaped U-M’s astronomical heritage, see the historic telescopes they used, and learn more about the University’s early days in Ann Arbor.

Tours depart regularly and last 30-45 minutes. Walk-ins visits are encouraged; no reservations are necessary. The last tour departs 30 minutes prior to closing or program change. 

The historic Observatory is wheelchair accessible with the exception of the dome. Assistive listening devices are available upon request.
