If you go to London it hard to miss the ever-present”Big Ben” (or as it is known now, the Queen Elizabeth Tower Big Ben actually refers to the largest bell). The clock tower that was erected in 1859 next to Westminster Palace chimes over the River Thames, and has become one of the city’s greatest landmarks. Not only that, it was also a beacon of hope for Londoners during the air raids of the Blitz, when it managed to survive with only a blown out dial on one side (the clock performed unfailingly throughout the Blitz).
But now the bells will chime no more for the next four years, which will be its longest period of silence to date. Starting on August 21, 2017, Big Ben will undergo a 29 million restoration to restore its iron roof and pendulum. The clock will be completely disassembled and cleaned as well, and all four of the dials will undergo restoration as well. However, the bell will still toll on special occasions such as Remembrance Sunday (November 11, 2017). You can read more about the restoration here.
