St. Marys Hospital

Saint Mary's Hospital is one of two hospitals in Rochester, Minnesota operated by the Mayo Clinic. It was founded in 1889 by a local Franciscan religious community led by Mother Alfred Moes, in partnership with Doctors William W., William J., and Charles H. Mayo.

Today it is a large hospital campus with 1,157 licensed beds and 53 operating rooms. The buildings comprising it are named after Franciscan sisters who were the hospital's administrators: Mother Alfred, Joseph, Domitilla, Mary Brigh, and Generose, as well as the Francis Building. The hospital includes the 85-bed Mayo Eugenio Litta Children's Hospital. The Mayo Clinic Psychiatry and Psychology Treatment Center in the Generose Building is also part of the campus.
