Is Wrexham's Pontcysyllte Aqueduct a wonder of the world? Should it be up there with the tourism greats, such as the Taj Mahal, the Pyramids of Egypt and the Serengeti?

The government thinks so, writes Vicky Baker. The aqueduct, regarded as one of Thomas Telford's best civil engineering achievements, is among its nominations for Britain's next World Heritage Site. Other hopefuls are the Antonine Wall, once the frontier of the Roman Empire in Scotland, and the north-east's twin monastery of Wearmouth and Jarrow, the former home to the Venerable Bede.

The UK currently has 27 World Heritage Sites - including Stonehenge, Hadrian's Wall, the Tower of London and Canterbury Cathedral. It is hoped all three of this year's nominations will be joining them.

Which UK sites would you like to see join the World Heritage list? Will you be rooting for one of the government's nominees? Or have they made a huge oversight that you want to share?
