List three column styles and where we would see examples of them in Washington DC

Answer:Corinthian columns are the most ornate, slender and sleek of the three Greek orders. They are distinguished by a decorative, bell-shaped capital with volutes, two rows of acanthus leaves and an elaborate cornice. In many instances, the column is fluted. Columns in this style can be found inside and outside of the buildings on Capitol Hill, including the U. S. Capitol, the Supreme Court Building, the Russell Senate Office Building, the Cannon House Office Building and the Library of Congress.
