In 2012, Lowell General merged with Saints Medical Center, adding a second campus to the hospital, and consolidating hospital care in the city under the Lowell General Hospital name. The hospital, now one of the largest institutions in the Merrimack Valley, has 407 beds. Saints Medical Center itself has a long history in Lowell, itself formed by the 1992 merger of St. Joseph's Hospital and St. John's Hospital. St. Joseph's Hospital, the oldest in the city, had been founded as Lowell Corporation Hospital in 1839.
