London by rail and see. Huge crowds gathered to watch it
being pulled across Westminster Bridge by 16 white horses.
During tests, however, a crack appeared and a new Great
Bell had to be cast. Though this one would eventually also
develop a crack, successful repairs and a lighter hammer
have ensured that it still rings out the time today.
The Neo-Gothic heritage of the Clock Tower is particularly
emphasized by the ornate decorations of its upper fl oors and
the clock dials. Each dial is seven meters (23 ft) in diameter
and made from cast iron and 312 separate pieces of pot opal
glass. Once every fi ve years, specialist technicians abseil
down the dials to carry out cleaning and essential repairs.
The clock mechanism is wound by hand three times a week
and is still as accurate today as when it was constructed
over 150 years ago. Although Big Ben is one of the most
famous tourist attractions, it’s not open to overseas visitors.
Residents of the United Kingdom are able to visit the tower
after arrangement with their local Member of Parliament.
