An extraordinary example of architecture serving a purpose are the aqueducts. The aqueducts employed the famous roman arches with the use of concrete. The Romans came up with this advanced system to solve the issue of having a consistent flow of water into the cities. This was really important because this water was used to supply important things such as their fountains, public bathing centers and toilets, and even some private homes. The Romans even had a sewer system that allowed for the waste water to be flushed out of the city keeping their city very clean. One of the most amazing things about the aqueducts is that with some repairs and connections some of them could still function today.
The Pont du Gard is an excellent and beautiful example of the Ancient Roman aqueducts. The Pont du Gard fits effortlessly into the natural landscape as it if it were always meant to be there. The Pont du Gar carried water by gravity across the river on a bridge of arches. The aqueduct provided each person in the city of Nimes with 100 gallons of water a day. The structure is impressive in its perfection and precision in the proportions and balance that have kept this structure standing for around 2000 years.
