Roman aqueduct
Rome's first aqueduct was built in 312 BC, and supplied a water fountain at the city's cattle market. By the 3rd century AD, the city had eleven aqueducts, sustaining a population of over a million in a water-extravagant economy; most of the water supplied the city's many public baths. Cities and towns throughout the Roman Empire emulated this model, and funded aqueducts as objects of public interest and civic pride, "an expensive yet necessary luxury to which all could, and did, aspire".
Aqueducts on the C&amp;O Canal
The Town Creek Aqueduct (#10), like the other aqueducts on the last , was begun in 1838, and had the contract abandoned and later another contractor began work (in 1847). It was completed in the Summer of 1850. The Western Maryland Railway constructed a bridge next to this aqueduct.
