The University of Illinois Observatory is undergoing renovations this summer that will bring back some historical features of the national landmark.
The project is supported by a grant from the National Park Service through the Save America’s Treasures program, which funds the preservation of properties designated to have national historical significance.
Bryan Dunne, observatory director and teaching assistant professor in the Department of Astronomy, said there are many parts to the renovation, including the return of a special viewing area and old transit.
