Located in the Blackstone Block of Downtown Boston, this flatiron building encloses Marshall Street on the Freedom Trail, creating a tight, pedestrian-oriented street that once covered old Boston. The Union Block (c.1842) is a Greek Revival commercial block which typifies this network of short, narrow streets which somehow survived Urban Renewal and the coming of the highway in Boston. The longest running occupant of the building was Ward & Waldron Paper Hangings, which from my understanding, made wallpaper for the estates of Beacon Hill which were being built on the other side of town. After successive ownership, atlas maps show the ownership of the building in 1888 conveyed to Massachusetts General Hospital, which still held title to it past 1938. The building is now home to Bell in Hand, an iconic local pub that was founded in 1795 at another location.
