There's so much to see and do in London, it's no wonder the illustrations of it varied more than with other cities. Still, there was one icon that stood tallest: Big Ben, London's iconic clock, which 33 percent of those surveyed drew.
Technically, it's the bell inside the Clock Tower that is Big Ben, and he still dongs at quarter-past, half-past, quarter-till and on the hour.
Constructed in 1859 (at the time, it was the largest four-faced clock in the word), the tower is connected to Westminster Abbey and stands 315 feet tall. As Queen Elizabeth celebrated her Diamond Jubilee in 2012, the tower was renamed in her honor as the Elizabeth Tower.
The remaining 57 percent of drawings are much more scattered. The Tower Bridge was a close second to the clock, with illustrations depicting the Queen and her palace, Buckingham, following behind.
Others think of grabbing a pint of beer or taking a ride on the Underground, aka the Tube, which is the name for London's subway system.
