What evidence do we have for the high quality of architectural workmanship during the Roman Empire?

Evidence for the high quality of architectural workmanship during the Roman Empire is found in the durability and sophistication of structures such as the Pantheon and aqueducts, which have stood the test of time. The use of advanced engineering techniques, including the development of concrete and the arch, allowed for innovative designs and large spans. Additionally, archaeological findings, such as detailed mosaic floors and intricate frescoes, showcase the skilled craftsmanship of Roman artisans. Historical texts, like those of Vitruvius, further highlight the emphasis on precision and aesthetics in Roman architecture.
