A hundred years ago, the lamplighters in London were very busy men. It was their job , every evening, to light thousands of gas lamps in the city and the gentle light from those lamps was all that lit the foggy streets of Victorian London. Nowadays, there are electric lamps in most London. They switch themselves on and off automatically and do the job of the lamplighter. But some parts of London still have their traditional gas lamps which look just the same, though there is an automatic clock in them for switching them on and off. So the lamplighter has just to reset it in each lamp once a week. There are 1.100 gas lamps in London. Most of them are in the parks and outside the Royal palaces. The Queen likes to preserve certain things coming down from the old good times and has gas lights outside Buckingham Palace. Westminster, the home of the Houses of the Parliament, has 400 , more than any other part of the capital. Naturally, traditions are important in that part of London and especially at the Temple where a lamplighter still goes round every evening to light the gas lamps by hand.
