By 1858 the sisters had raised enough funds to build a convent next to Mount Saint Mary's Church.

It became a girls' Secondary Modern in 1946, at the same time as St Michael's College became a Grammar School.

[citation needed] There are three main buildings at Mount St Mary's, one is the oldest building consisting of most parts of the school, one is home to many important parts to the school and is split in half and the last one is the sports department.

Catholic education after 16 is found at Notre Dame Catholic Sixth Form College (former Notre Dame Collegiate School, the other girls' direct grant grammar school in Leeds).

It is situated just north of the A61, next to the derelict church of Mount St Mary which opened in 1857 and closed in 1989.
