Boy, 10, pulls plug on aqueduct
A 200-year-old aqueduct has been drained, sending millions of litres of water cascading into the river below.
David Halligan, 10, won a competition to pull the plug at the Pontcysyllte aqueduct, in north Wales.
Thomas Telford's 200-year-old structure is a World Heritage Site and is emptied every few years for maintenance reasons. It is drained by pulling a plug in the middle of the structure.
Secret source of a Roman aqueduct discovered
The Romans were masters of plumbing on a very grand scale and built massive aqueducts which allowed entire cities to be supplied with fresh water.
Most of them still work today, but the source of one of them has been a mystery that has vexed archaeologists.
Now, after three years of digging, the secret has been revealed.
Duncan Kennedy reports from Rome.
