Stock Photo of Roman Bath Aqueduct
Thermal spring water flows through an aqueduct at the Roman Bath of the city of Bath, England. This is the point at which hot water that was not required for use in the bathing establishment flowed from the Spring into the great Roman drain. From there it was carried to the River Avon a few hundred metres away.
The water flows through a sluice that could be regulated to completely drain the Sacred Spring and give access to the reservoir chamber for maintenance. The same system devised by Roman engineers continues in use today, nearly two thousand years after it was first built.
