The George R. Wallace Astrophysical Observatory was dedicated in the fall of 1971. It is named for a member of the MIT Class of 1913 who supported construction of the observatory.
There are six telescopes mounted on permanent concrete piers at the site. The two original, and largest, telescopes at Wallace, the 24-in and the 16-in Cassegrain reflectors, each have their own domes. Four 14-in telescopes are housed in an observing shed with a robotic roll-off roof.
The main building at Wallace has a restroom with shower, a kitchenette area, a common room, a bunk room, a work room which doubles as the observer's control room for the 24-in, and a machine shop area. The site also features a paved driveway, ideal for setting up portable equipment and telescopes.
