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".
Longdon-on-Tern Aqueduct
The cast iron canal aqueduct was designed by Thomas Telford and built in 1796 to carry the Shrewsbury Canal across the River Tern near Longdon-on-Tern in Shropshire. The aqueduct was opened one month after Benjamin Outram's cast iron Holmes Aqueduct on the Derby Canal, the world's first cast iron canal aqueduct. Since the closure of the Shrewsbury Canal in 1944, the aqueduct has been disused. The aqueduct is an Historic England Grade I listed building and has been on the register since 30 March 1971.
