Andrea Palladio was an influential Renaissance architect who developed a classical style inspired by Roman architecture. He is known for designing villas and churches with symmetrical facades and proportions based on Roman temples. His most famous works include the Villa Barbaro, with its symmetrical wings and central block resembling a temple front, and the Basilica Palladiana in Vicenza, which features a brilliant white facade with superimposed pediments and engaged columns supporting the nave. Palladio's designs emphasized symmetry, harmony of proportions, and references to classical antiquity.
