The Abbey Basilica of Mary Help of Christians is the center of the campus. It is German Gothic-Revival in design, and was the largest Catholic Church in the state at the time of its erection. The Benedictine monks of Belmont did much of the construction work themselves. The interior of the Church was completely renovated in 1964-1965. The Church held cathedral rank from 1910 to 1977.
Guests are welcome at all of the monks' liturgies.
A schedule is posted. In July 1998 the Church was named a Minor Basilica by Rome to recognize the church's historic and aesthetic importance. This building formerly housed the Abbey's music programs. Today it houses offices of the Adult Degree Program. The second floor is home to the Abbey Archives, will collections representing the 125-year history of the monastery and college.
