In 1892, the monastery relocated to Bedford Park Boulevard and Bainbridge Avenue, two blocks east of the Grand Concourse, in the Bronx.

In 1854, John Casper Metzler, C.Ss.R., the first pastor of the German-speaking Church of the Immaculate Conception, requested that a group of Ursulines from St. Louis, Missouri, come to his new parish in Melrose, then the southern tip of Westchester County, to teach girls.

As their first missionary community had grown quickly, the nuns visited the village of Melrose and accepted the invitation with the permission of their archbishop, Peter Kenrick.

At the time the nuns arrived, Morrisania was a sparsely populated, brand new suburb of the City of New York, the result of a series of decisions by members of the Morris family to open their estate lands for development.

With the changes in the life and structures of Roman Catholic religious institutes in the 1960s mandated by the Second Vatican Council, the Ursulines began to shed many of the monastic practices which had been imposed on them in the 16th century.

By the start of the 21st century, the nuns at the Mount had been so decreased in numbers through retirement and death, that the community chose to transfer to their regional headquarters located in New Rochelle, New York.

In 2011, a piece of the monastery portion of the property was developed into Serviam Gardens, an affordable senior housing complex with 243 units, planned also to serve as a model of green energy architecture.

The students are required to complete a certain number of hours volunteering, often on Sundays together with boys from Cardinal Hayes High School.
