'The old patent office building'
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.
