The Romans basically invented concrete, which came to be known as Roman concrete (opus caementicium). The interesting part that made Roman concrete so durable and long-lasting was that they used volcanic Italian sand, “also known as pozzolana.” (Khan, 2017) The other part that made this such a fine building material was that it could be set underwater, practically unheard of for that time. In addition, when this pozzolana was combined with other pieces such as stones and bricks, it allowed large and very strong structures to be built.

The arches were important in other ways besides beauty; they supported waterways. Arches became a part of the aqueduct system in Rome; there were approximately 11 aqueduct systems in Rome. (Roda, 2016) “The most famous aqueduct in ancient times was the Claudian aqueduct, begun by Caligula and finished by Claudius.” (Kamm, 2017) The arches were only part of the systems in some places because they only need to be in place where there were large valleys or gullies. Of the 315 miles of Roman aqueducts, only 36 miles were supported by arches. (Roda, 2017)
