ANN ARBOR, Mich. (AP) -- The University of Michigan has plans to upgrade the second-oldest building on the Ann Arbor campus.
The Ann Arbor News reports the university's Board of Regents has approved the design for a $10 million upgrade to the Detroit Observatory. The building was constructed in 1854 as the school's first dedicated scientific research lab. The project includes a classroom addition, reception area, storage and a new elevator. Construction is scheduled to be done in fall 2020.
The building has had previous additions in 1868 and 1908. It was restored in 1999. The university says it's the oldest remaining observatory in the U.S. to have its original telescopes from the 1850s in working condition and on their original mounts. The building is listed on the National Register of Historic Places.
