The Capitol buildings and grounds reflect thousands of years of architecture styles. This includes the well-known and iconic neoclassical style of the Capitol to the Art Deco styles of the Library of Congress Jefferson Building. At the Architect of the Capitol, perhaps no other responsibility is as crucial as ensuring these buildings are preserved in the awe-inspiring manner in which they were first conceived and constructed.
