Ancient Roman aqueducts were
large bridges with pipes or channels set into them. These pipes carried
water from rivers and lakes around the country, into Rome and other urban
centers. One famous ancient Roman aqueduct that still remains today is the
Pont du Gard in France.
"I rebuilt aqueducts in many places that had decayed with age, and I doubled the capacity of the Marcian aqueduct by sending a new spring into its channel."
- Augustus Caesar (14 A.D.)
