For decades, the primary entrance to Maine General Hospital was a circular driveway off Arsenal Street, shown here in a photo taken from the upper level of the 1956 Pavilion. The portico was added to the entrance in 1903, when a new surgical pavilion was built to accommodate updated procedures and meet modern standards. The portico was removed in 1974 when the Southern Maine Radiation Therapy Institute was built.

Maine General Hospital is the predecessor of Maine Medical Center.
