Planetarium prior to the start of the 2021 renovation.

1 of only 3 Public Planetariums in the State of Iowa with public programming

The Planetarium has been part of the Grout Museum of History & Science since it opened in 1956

The old projector was installed in 1976 and was no longer operational

The Museum holds over 500 shows per year serving over 4,500 visitors


After nearly 50 years in service, the planetarium at the Grout Museum District has undergone a much-needed facelift. This work was made possible through the generosity of Barbara Corson, Black Hawk County Gaming Association, Roy J. Carver Charitable Trust, R.J. McElroy Trust, Cathy Livingston Fund (Community Foundation of Northeast Iowa,) The Leighty Fund, Sandra Rada-Aleff, Sally Darragh, Kathy Breckunitch, Frederick W. Mast Family Fund and Greg & Lynette Harter.

 The project is a nearly-complete renovation of the planetarium; only the original dome remains (with a fresh coat of paint of course). New elements include comfortable seating, 4k projector, upgraded lighting, electrical, sound system and carpet. Most of the work was completed by Bowen Technologies of Indianapolis. 

First part of the renovation process, which involved removing the existing bench seating.

Freshly painted dome and new carpet installed.

Finished renovation.
