In fact, Big Ben is the largest of the six bells of Westminster Palace in London. But it has long been associated with the name of the Clock Tower, which in September 2012 was officially called “Elizabeth Tower”. The decision to rename the tower was made by the British Parliament to mark the 60th anniversary of the reign of Queen Elizabeth II.
The tower was built in 1858. The project architect was Augustus Pugin. The height of the tower and spire is 96.3 m.
