Constructed in 1963 as the first female residence hall at Le Moyne, St. Mary's is a 44,000 square-foot, five-story residence hall. Double and single rooms share two community bathrooms on each floor along with a laundry room; triple rooms include their own bathrooms. Rooms include built-in closets, dressers, vanity areas, desks, desk chairs and beds. The building was renovated in 2001, which included remodeled rooms, an internal sprinkler system and updated classrooms on the first floor, often used for living-learning communities. A 24/7 computer lab is located on the first floor. The basement of the residence holds a student lounge with a full kitchen, a large-screen television, couches and chairs, tables, vending machines and a pool table. The building is connected to Harrison Hall via an enclosed walkway, providing an easy way to access the fitness room on the first floor of Harrison.
