It's summer in Michigan, and you know what that means—construction! From its initial build in 1854, to the 2022 addition, the Frankel Detroit Observatory is no stranger to the rebuilding of campus infrastructure. The first photo, from 1997, shows workers refinishing the historic dome, home to the 1857 Fitz telescope, which you can still visit today!

Though it may look like a work zone in front of our Observatory Street entrance, we are open this week for our usual hours, Thursday 12-5 pm, Friday 12-11 pm, with nighttime telescope observing 9-11 pm on Friday (weather permitting).
