Big Ben first rang across Westminster on 31 May 1859. A short time later, in September 1859, Big Ben cracked. A lighter hammer was fitted and the bell rotated to present an undamaged section to the hammer. This is the bell as we hear it today.
Elizabeth Tower stands at more than 96 metres (105yrds) tall, with 334 steps to climb up to the belfry and 399 steps to the Ayrton Light at the very top of the tower.
Big Ben is found in the Elizabeth Tower at the north end of The Houses of Parliament in Westminster, Central London, next to the river Thames.
There are a several London bus routes that go past the tower, and Westminster Tube station is directly across the road, serviced by the Jubilee, District and Circle lines. Westminster pier is next to the tower and is served by a number of river bus travel options.
