Renaissance architecture, born in 15th-century Italy, revolutionized building design. It emphasized symmetry, proportion, and classical elements, reviving Greek and Roman styles. This movement reflected the era's cultural shifts, embracing humanism and renewed interest in antiquity. Key figures like Brunelleschi and Palladio shaped Renaissance architecture's development. Their innovative designs, such as the Florence Cathedral dome and Villa Rotonda, exemplified the style's principles. These ideas spread across Europe, influencing urban planning and leaving a lasting impact on Western architecture.
