Renaissance artists were influenced by ancient Greek and Roman architecture because many of them traveled to places where these ancient structures still stood, especially in Italy and parts of the Mediterranean.

This exposure helped revive classical ideas in art, leading to a focus on humanism, perspective, and realistic depictions in art, which were key characteristics of the Renaissance.
