Modern architecture is a style that emerged in the early 20th century, characterized by simplicity, clean lines, and a focus on function. It often utilizes new materials like steel and glass, allowing for innovative designs and open spaces. This movement aimed to break away from traditional architectural styles, embracing minimalism and the idea that form should follow function. Key figures in modern architecture include Le Corbusier and Ludwig Mies van der Rohe, who emphasized the importance of space and light in their designs. Iconic examples of modern architecture include the Villa Savoye and the Seagram Building, showcasing the movement's principles of efficiency and aesthetic clarity.
