The decline in the interest of boarding military academies and the high cost of monthly tuition, was the principal cause of the school's demise.
The St. Patrick's campus was originally built in 1922, when the Pallottine Sisters opened the Mother House of the United States.
In 2013, in anticipation of selling the property, the entire St. Patrick Military Academy Campus, including the Sister's Residences and Old Chapel were demolished.
The Bishop came to the school each Easter for Confirmation and Monsignor Sullivan took care of First Holy Communion.
Mass was said for the Regiment on Sunday if it was a closed weekend with no free time at home.
The school also sent partial units to include the color guard and the marching band to local Memorial Day events in Monroe, New York.
