The William Donald Schaefer Building, also known as the "William Donald Schaefer Tower" or simply the Schaefer Tower, is a skyscraper at 6 Saint Paul Street, on the northwest corner with East Baltimore Street in the City of Baltimore, in Maryland. The building rises 37 floors and 493 feet (150 m) in height, and stands as the third-tallest building in the City. If the flagpole positioned atop the building, which reaches 590 feet, is included, the building would be the tallest in the state (flagpoles are normally not counted when determining architectural height). The nine upper floors are unoccupied and contain a spiral staircase to the top floor. The flags flown from the Tower's poles are landmarked throughout the downtown area by flying (by order of current Governor Martin O'Malley, by an extremely large and noticeable "Star-Spangled Banner Flag" of fifteen alternating red and white stripes and fifteen stars used by the nation between 1795 and 1820, and flown over the city and Fort McHenry during the British attack in the War of 1812 during September 12-13-14, 1814, during the historic Battle of Baltimore, when Georgetown and Frederick County lawyer/poet, Francis Scott Key held on an off-shore U.S. truce ship anchored among the bombarding British Royal Navy fleet, saw the flag raised that following morning over the embattled fort and eventually was inspired to write the words to a poem, initially known as "The Defence of Fort McHenry" and later renamed the "Star Spangled Banner" when put to music a few days later, which became the national anthem in 1931. In addition, a slightly smaller uniquely-designed Maryland state flag of black/gold and red/white colors flies just beneath the larger American banner, highest in the state.
