Big Ben

Big Ben

The Clock Tower is the name of the famous tower of Parliament - more popularly known as Big Ben. UK residents can arrange a tour through their local MP. However, please be advised that space is extremely limited and early booking, 3-6 months in advanced, is strongly recommended. Overseas visitors cannot currently visit the tower.

Big Ben is one of London's best-known landmarks, and looks most spectacular at night when the clock faces are illuminated. You even know when parliament is in session, because a light shines above the clock face.

The four dials of the clock are 23 feet square, the minute hand is 14 feet long and the figures are 2 feet high. Minutely regulated with a stack of coins placed on the huge pendulum, Big Ben is an excellent timekeeper, which has rarely stopped.

The name Big Ben actually refers not to the clock-tower itself, but to the thirteen ton bell hung within. The bell was named after the first commissioner of works, Sir Benjamin Hall.

This bell came originally from the old Palace of Westminster, it was given to the Dean of St. Paul's by William III. Before returning to Westminster to hang in its present home, it was refashioned in Whitechapel in 1858. The BBC first broadcast the chimes on the 31st December 1923 - there is a microphone in the turret connected to Broadcasting House.

During the second world war in 1941, an incendiary bomb destroyed the Commons chamber of the Houses of Parliament, but the clock tower remained intact and Big Ben continued to keep time and strike away the hours, its unique sound was broadcast to the nation and around the world, a welcome reassurance of hope to all who heard it.

There are even cells within the clock tower where Members of Parliament can be imprisoned for a breach of parliamentary privilege, though this is rare; the last recorded case was in 1880.

The tower is not open to the general public, but those with a "special interest" may arrange a visit to the top of the Clock Tower through their local.

When most people heat the words "Big Ben" they immediately conjure up an image of the striking Victorian Gothic structure of the clock tower of the Palace of Westminster (the Houses of Parliament). Let's clear up a common misconception first; technically speaking, the name "Big Ben" does not refer to the famous tower, nor to the four huge clock faces of this London landmark; instead, it refers to the largest of the five bells inside the clock tower, whose chimes are such a familiar sound to listeners to BBC radio over the years.

The tower was begun following the disastrous fire which destroyed the old Palace of Westminster in 1834. Charles Barry was given the contract to rebuild the Palace, and his designs included a clock tower.

The Tower

The clock tower of the Palace of Westminster took 13 years to build, and was completed in 1856. The tower is 316 feet high. The spire that rises above the belfry is built with an iron frame, and it is this frame which supports the weight of the bells. A staircase rises up inside the tower, and a climb is rewarded by excellent views from the belfry level. Several small rooms are built into the lower part of the tower, including a small prison cell.

The Clocks

The cast iron frame of the clock face was designed by AW Pugin, who was responsible for much of the Gothic decorative elements of the Palace of Westminster. The dials are 23 feet in diameter and the faces themselves are not solid, but is composed of many small pieces of opal glass, assembled like a stained glass window. Several of the central pieces of glass can be removed to allow inspection of the hands from inside the clock tower. The numbers on the clock faces are each two feet high. An inscription in Latin below each clock face translates as "God save our Queen Victoria I".

At the time of its construction the clock mechanism was easily the largest in the world, and it is still among the largest today. The clock mechanism, designed by Edmund Beckett Denison, has proven to be remarkably accurate over the years, allowing small adjustments to the clock's rate to be made by placing pennies on a small shoulder of the clock's pendulum!

The Hour Bell

Big Ben - the hour bell - is said to have been named after Sir Benjamin Hall, Commissioner of Works, who was known for his bulk, as is the bell! The first Big Ben hour bell was complete before the tower, so the bell was hung in New Palace Yard. After repeated public ringing the bell cracked, and had to be replaced by the current bell.

The bell had to be placed in a special wooden frame, turned on its side, and hoisted up the centre of the tower to the belfry. So heavy was Big Ben that the process took over 36 hours to complete. The bell began ringing the hours in July of 1859, but it cracked after only two months of use. Instead a recasting the bell, it was simply given a quarter turn, and a lighter hammer used to strike the hours.

The Chimes

The first BBC radio broadcast of the Big Ben chimes was on New Year's Eve, 1923. Later, permanent microphones were placed in the tower, and the sound of Big Ben became a familiar one to listeners, assuming great significance during WWII, when the chimes became a symbol of hope and home to BBC World Service listeners around the world.

The best time to see Big Ben may be at night, when the clock faces are illuminated, as is the facade of the Palace of Westminster facing the Thames. The effect from Westminster Bridge or the far bank of the Thames can be breathtaking.
