Property Features
Since its construction, the Pine Bluff Observatory has been, and continues to be, an important research facility for the University of Wisconsin-Madison. The observatory was built in 1958, during the Space Race of the mid-twentieth century when there was an increased interest in astronomy and space exploration. The Observatory was built to replace the Washburn Observatory, whose facility and telescope (refracting with curved glass) were becoming obsolete as astronomers were using larger telescopes. Because the Pine Bluff Observatory is associated with the Space Race, an event that made a significant contribution to the broad patterns of history, it is recommended eligible under Criterion A. The building is not associated with the lives of past significant persons and is therefore not eligible under Criterion B. The Pine Bluff Observatory retains its original design, materials, and function and is a distinctive example of an astronomical observatory built during the Space Race of the mid-twentieth century. Therefore, the building is recommended eligible under Criterion C. The observatory retains its historic and architectural integrity of design, materials, and workmanship. For these reasons, it is recommended potentially eligible for the NRHP and may warrant further investigation.
