Clifton Suspension Bridge? That's in San Francisco, right? An embarrassing number of Britons cannot tell the difference between the UK's landmarks and those situated in foreign countries, research suggests. More than half of us (55%) confuse the Lake District's Wastwater lake with Lake Geneva in Switzerland, while Portsmouth's Spinnaker Tower is believed by 48% to be in Dubai, a survey found. San Francisco's Golden Gate Bridge Bristol's Clifton Suspension Bridge, designed by the Victorian architect Isambard Kingdom Brunel, is misidentified by one in 10 Londoners as San Francisco's Golden Gate Bridge. The poll of 2,000 UK adults by First Great Western, the train operator, also found that Christchurch College, one of Oxford University's best-known institutions, is thought to be in France by 16% of Britons, while the world-famous open air Minack Theatre in Porthcurno, Cornwall, is believed to be in Athens, Greece, by almost a third (32%). Appletree Bay, a picturesque spot on the Isles of Scilly, was located by 30% in the Maldives instead. Almost one in 10 attributed images of the Isles of Scilly to East London's Isle of Dogs. Philip Edgerton, head of marketing at First Great Western, said: "We live in a fantastic country but this research shows that many of us simply aren't aware of the amazing places on our doorstep just waiting to be discovered." Previous research by Travelodge found that a third of Britons mistook the Roman-built, Hadrian's Wall for the Great Wall of China, more than half confused London's Trafalgar Square for a Spanish or Portuguese piazza and a similar number were unable to identify London's Canary Wharf, instead mistaking it for the New York City skyline.
