Like many buildings, monuments and memorials in Washington DC,
the design for the United States Capitol was the result of a design
competition. The challenge to design the United States Capitol
was won by Dr. William Thornton for his simple Greek stlye. This
was elaborated further by other architects before construction
began in 1793. Over the following decades large sections of the
Capitol were completed although some were destroyed by British
troops in 1814. The US Capitol was finally completed in 1826.
