Tate Hall is the home of School of Physics and Astronomy, including the Minnesota Institute for Astrophysics. Construction on the building (then known as the Physics Building) began in 1926, and it has seen various additions and renovations over the intervening years. The most recent of these was a $9.25 million project undertaken in 2017. The main façade of the building, which faces Northrop Mall, was preserved, while a significant inner portion of the building was replaced with new construction. The building includes 29 teaching labs and 10 research labs for the School of Physics and Astronomy, as well as the University’s historic observatory housing a 10½″ refracting telescope still used for our Institute's Public Observing Nights.
