Built in 1898 as a residence for James Monaghan, an early supporter of Gonzaga and St. Aloysius Church, it was considered one of the finest homes north of the Spokane River. The mansion was acquired by the University in 1942 as a music conservatory and has served as the home to the music department ever since. The building serves as the main music headquarters, holding the music department office, a large classroom, lounge, faculty offices, computer technology lab, class piano lab and practice rooms.
