Palace of Westminster, London, England 15 May 2025

London"s most famous clock tower isn"t called Big Ben—that name belongs to the massive 13.5-tonne bell inside. It has marked time for Londoners since 1859, ringing from what is now known as the Elizabeth Tower. In 2012, officials renamed the Clock Tower as Elizabeth Tower to honour Queen Elizabeth II during her Diamond Jubilee. The clock has stopped only for maintenance and rare disruptions, such as bomb damage during World Wars I and II. Each of its four clock faces spans 6.9 metres, with the minute hands measuring 4.3 metres. At 96 metres tall, the tower is part of the grand Palace of Westminster, home to the UK Parliament.
