Big Ben @ 150
The bell, cast in Whitechapel on 10 April 1858, was first rung in the Great Westminster Clock on 31 May 1859. It is the world’s largest four-faced, chiming clock and the third largest free-standing clock tower in the world.
The design for the Clock Tower was Pugin’s last design before his final descent into madness - the first of many such descents to occur in the immediate vicinity.
Because of changes in ground conditions since construction (notably tunnelling for the Jubilee Line extension), the tower leans slightly to the north-west, by roughly 8.66 inches at the clock face, giving an inclination of approximately 1/250, making it like many of the crooked individuals in the area.
Due to thermal effects (an unusually high incidence of hot air in the locality?) it oscillates annually by a few millimetres east and west, twisting and turning in the political weather.
No wonder it is such a symbol of our Parliament.
