Jeffersonian architecture

Jeffersonian architecture is an American form of Neo-Classicism and/or Neo-Palladianism embodied in the architectural designs of U.S. President and polymath Thomas Jefferson, after whom it is named. These include his home (Monticello), his retreat (Poplar Forest), the university he founded (University of Virginia), and his designs for the homes of friends and political allies (notably Barboursville).
