Andrea Palladio was an influential Italian architect born in 1508 in Padua. He is best known for his classical style, which drew inspiration from ancient Roman architecture. Palladio's designs emphasized symmetry, proportion, and the use of columns, making his work highly regarded during the Renaissance. His most famous buildings include the Villa Capra, also known as the "Rotonda," and the Teatro Olimpico in Vicenza. Palladio's architectural principles were documented in his book, I Quattro Libri dell'Architettura, which has inspired architects worldwide, including those in the United States during the 18th century.
