Julia Bradbury explores the wonder of the Industrial Revolution, visiting the Pontcysyllte aqueduct, which carries the Llangollen canal over the valley of the River Dee near Wrexham. Completed in 1805, it is the longest and highest aqueduct in Britain and is now categorised as a Grade I listed building. She also boards Brunel's former passenger steamship the SS Great Britain and appreciates the gothic majesty of Manchester Town Hall and the iconic fun of Blackpool Tower.
