The Oscar Meyer Observatory, a designated Fitchburg Historical Landmark, was constructed in 1879 on the University of Wisconsin campus and now straddles the ridge between Eagle School and the Faraday Center.

Built in 1879 the observatory hosted the largest telescope of its era, with a 15.6 inch lens.  The observatory was then located on its Lake Mendota campus site, until 1959 when the University planned to destroy the building.  The structure was saved by the efforts of the Madison Astronomical Society, when Reynolds Moving Company moved the building to its current location.  The move was primarily funded by Oscar Mayer Sr., and the observatory was named after him.

The Madison Astronomical Society used the building until the mid-1980's when they decided to move their equipment to Brooklyn, Wisconsin to avoid the light pollution from encroaching development. The building has been unused since then.

Plans are currently underway to restore the exterior of the building.  James Sewell of the State Historical Society is working closely with Fitchburg Center to ensure the period and historical significance of the building will be honored.
