Palladianism is an architectural style inspired by the works of the Italian architect Andrea Palladio, who lived in the 16th century. This style emphasizes symmetry, proportion, and the use of classical elements such as columns and pediments. Palladian buildings often feature a central block with a portico and are designed to harmonize with their surroundings. The movement gained popularity in the 17th and 18th centuries, particularly in England and North America. Notable examples include Chiswick House in London and Monticello, the home of Thomas Jefferson. Palladianism influenced many architects and remains a significant part of classical architecture today.
