Thomas Jefferson was a large follower of neoclassicism, and made the architecture of the government buildings follow the neoclassical themes and designs. Neoclassicism is a movement that stylizes romantic elements from the classical age (Ancient Greece, Rome) that influences the design of buildings, arts, etc. Jefferson was a supporter of the movement, designing his own home at Monticello with Greco-Roman influence as well as most government buildings in the US.
