'The old patent office building'

image9

Construction on 'The Old Patent Office Building' in Washington DC began in 1836.  It stands today as a historic site covering an entire city block.  Its massive size was due to earlier patent regulations requiring a scale model of every invention to be stored on site.  During the civil war the building served as a hospital and barracks.  It was also the site of Lincoln's second inaugural ball.  Today The Old Patent Office Building houses the Smithsonian American Art Museum and the National Portrait Gallery.
