Mount Saint Mary's Convent and Academy

Mount Saint Mary's is a three-story structure built with stone on the lower level and brick walls above, designed in the Georgian architectural style. The building occupies a notable position in Grass Valley and now operates as a museum displaying the rooms and objects from its earlier use.

The Sisters of Mercy founded the building in 1865 as an orphanage and convent under the guidance of Bishop Eugene O'Connell. For nearly seventy years it served the growing needs of abandoned and vulnerable children in the northern mining region of California.

The rooms inside reflect how religious sisters and orphaned children lived together in this place, with classrooms and shared spaces showing the rhythm of daily care and learning. You can sense how education and spiritual life were woven into every part of the building.

The building operates as a museum with seasonal hours that change throughout the year, offering more limited access during the colder months. Plan your visit in advance and allow time to walk through all the rooms and see the historical items displayed inside.

The building was simultaneously known as both Sacred Heart Convent and Holy Angels Orphanage, reflecting how one place served as both a religious community home and a care facility for children. This dual purpose shaped the layout, with spaces designed for both prayer and practical education happening side by side.
