Palladian Architecture is a style of building that originated in the 16th century, inspired by the works of the Italian architect Andrea Palladio. It emphasizes symmetry, proportion, and the use of classical elements like columns and pediments. This architectural style often features grand facades and open spaces, creating a sense of harmony and balance. The influence of Palladian Architecture spread throughout Europe and into America, leading to the construction of many notable buildings. Key characteristics include the use of a central portico, large windows, and a clear geometric layout. This style remains popular in various forms today.
