Originally a boarding school, the academy began accepting day students in 1911.

[1] In response to the growth of the school and evolving educational needs, the Mount moved in 1961 to its present site, just outside the community of Chestnut Hill near Philadelphia.

A private day school for girls in grades nine through twelve, the Mount offers a college preparatory education in a Catholic context.

The school building, which was constructed during the 1960s, offers classrooms, a cafeteria, 600-seat auditorium, gymnasium, chapel, and choir room.

The school's celebrated crew team rows out of a Conshohocken boathouse along the Schuylkill River.
