St. Paul's Cathedral, London

Built in the 17th century, St. Paul’s Cathedral is one of London’s most famous and most recognizable sights. The Cathedral was heroically saved by firefighters when it was bombed during the Second World War. Its impressive dome was inspired by St Peter’s Basilica in Rome and rises 118 meters (365 ft) to the cross at its summit. It was the tallest building in London from 1710 to 1962, and its dome is also among the highest in the world.
