 The landmark McCauley Tower building of the hospital along St. Paul Place to the west of North Calvert Street, opened in 1963 and is located at 301 St. Paul Place.Its form was quite unusual in that the upper two-thirds of the building of tan/light brown bricks spread out fifty yards out above the lower five stories.Additionally the later Mary Bunting Tower skyscraper buildings and annexes further north along the east side of St. Paul Place and North Calvert Street to East Pleasant Street, and to the next block at the elevated Orleans Street Viaduct (over Bath Street) were built in the mid-2010s with additional parking garages attached to the east along Guilford Avenue.
