  • Wonderful piece of history. The campus is still active with students from the University of Chicago. The school and historical society put on real amazing star gazing nights. It is a great stroll through history with the tours they offer.
  • This is a really beautiful historic building, and our tour was interesting and our tour guide a very kind and enthusiastic man who obviously enjoys what he does. Excellent tour. The woman in the gift shop was rude, and then she shorted me $20 on my change, balling it up with my receipt and shoving it into my hand at the same time as my items. Unfortunately I didn't notice until we we're well down the road, so I didn't get to confront her. But you can't let one bad egg ruin the basket, and all in all it was a really nice visit and our tour guide really was fantastic, so I'm still giving it 5 stars. 😊
  • 9.1.17 We had a wonderful experience at the special 40'' telescope tour! Dan our astronomer guide gave us plenty of viewing time and taught us very interesting facts about Saturn, the moon, binary stars and globular clusters. It was also great getting to see the beautiful Observatory too. Be sure when you go to be very respectful of other guests and the guide by being good listeners and following directions.
  • While I was familiar with the history of the telescope, I had no idea that the building's architecture was as fascinating as it is! The docent was very knowledgeable and willing to answer whatever questions we had. If you like architecture and/or astronomical history, you need to visit this place!
  • Enjoyable place to visit to learn about history and the Stars. Tour guides are full of lots of great information. Gift Shop full of great items - much improved
