Travel Trivia Tuesday 5

Well done once again to Claire. The Lisbon monument pictured in last week's trivia quiz is indeed the Belem Tower.Now for today's question - and it's another illustrated one. Portugal doesn't just offer beautiful sandy beaches, cultural heritage and some of the best golf courses on the planet (although they are reason enough to visit). It's also home to some amazing modern architecture.Lisbon is home to the longest bridge in Europe. First opened in 1998, it is 11 miles long and was built at a cost of one billion US dollars. It's so vast that apparently engineers had to factor in the curvature of the earth during its construction. But what is it called? Clue: it takes its name from a famous Portuguese explorer. As always, the answer will be revealed next Tuesday.
