Big Ben, Palace of Westminster, London
Click photo to enlarge.
It's a bit of a misnomer that the clock, clock tower, or even the attached Houses of Parliament are labeled 'Big Ben.' In fact, the source of the nickname is...
A bell. The Great Bell of the Great Clock of Westminster is supposedly named after either civil engineer Benjamin Hall, 1st Baron Llanover (who oversaw the installation of said bell) or boxing heavyweight champion Ben Caunt (a bare-knuckle boxer).
Yes, it is cliché to have a photo with, just as La Tour Eiffel or Il Colosseo for Paris and Rome. Yet, as one exits the Jubilee Line at Westminster from the Tube, the famous tower dominates the sky over the underground entrance. As the world's largest chiming four-faced clock tower that just celebrated its 150th anniversary shortly before this photo was taken, I say cheers!
