Cleaners have been busy scrubbing the clock on the Elizabeth Tower at Westminster Palace.
Many people know the landmark as Big Ben - which is the nickname of the bell inside the clock tower.
The tower was named Elizabeth Tower in 2012 to celebrate the Queen's Diamond Jubilee.
The clock hands were frozen at 12:00 so the four cleaners could abseil in front of the clock face.
