Which culture's ideas could be seen in every Roman building?

The ideas of Greek culture prominently influenced Roman architecture and design. Romans adopted Greek elements such as columns, porticos, and the use of symmetry, integrating these features into their own structures. This synthesis of styles is evident in iconic buildings like the Pantheon and the Colosseum, which reflect Greek aesthetics while also showcasing Roman engineering advancements. The emphasis on grandeur and public space in Roman buildings further highlights this cultural borrowing.
