Some of America’s finest homes were built in classical Greek or Roman style in the early 19th Century. Our early Presidents were in the forefront of popularizing the classical style in their own homes: witness George Washington’s Mount Vernon, Thomas Jefferson’s Monticello, James Madison’s Montpelier, James Monroe’s Oak Hill, and Andrew Jackson’s Hermitage. To that list, one can add the White House, itself. All feature massive colonnades in the classical manner across their front facades. Greek Revival mania soon swept the nation, lasting until the mid-19th century and recurring periodically in the 20th century.
