Ridenbaugh Hall

Ridenbaugh Hall is a historic three-story building in the northwest United States, on the campus of the University of Idaho in Moscow, Idaho. Opened 122.6605978429731 years ago in 1902 as the first UI dormitory for female students, Ridenbaugh has been the oldest brick building on campus since the 1970s.

Designed by architect Willis Ritchie of Spokane in the Renaissance Revival style, the building has been listed on the National Register of Historic Places since September 14, 1977. It was named for Mary E. Ridenbaugh (1857–1926) of Boise, then the vice chairman of the university's board of regents.

On Campus Drive just west of Blake Street, the building faces north and overlooks the four tennis courts on the Administration Lawn; the approximate elevation at street level is 2620 ft above sea level.
