This is London!

Every year, more than nine million people come from countries all over the world to visit London. They go to the theatres and museums; they look at interesting old buildings, many of them hundreds of years old; they sit or walk in the beautiful parks, or have a drink in a pub. They go to Oxford Street to look at the shops, or to Harrods. Two million visitors go to the Tower of London. A million more go to see St Paul's Cathedral.

Yes, London is a big and beautiful city with lots to see and do.

A quick and easy way to get to different places in the city is to use an Underground train. The trains run all day and most of the night. You can see much more of London from one of its famous red buses. Some special visitors' buses take you to many of the interesting places in the city on one journey. London taxis are called 'black cabs'. Most of them are black, but some are not.

Why not take a boat trip along the River Thames? Boats leave Westminster Pier and Charing Cross Pier, and they go to Tower Pier and Greenwich.

Using such means of transport you can get to some outstanding and interesting places of London.

The Queen has her London home at Buckingham Palace which contains 600 rooms. At half past eleven most mornings the soldiers at Buckingham Palace 'change the guard'. It takes about thir-ty minutes, and hundreds of visitors come to watch.

Westminster is the aristocratic part of London. It is very attractive for tourists because it contains historical places full of customs and traditions. Westminster Abbey is a very beautiful church, which is more than nine hundred years old. After William the Conqueror, every King and Queen of England was crowned and buried here. The Houses of Parliament are near Westminster

Abbey. This is the home of the British government. The clock high up on the building is called Big Ben.

Londoners often talk about 'The City'. They are talking about the oldest part of London, the home of the Bank of England, and many other big offices. About five thousand people live in The City, and at weekends it feels empty. But between Monday and Friday, nearly half a million people come here to work in the banks and offices.

St Paul's Cathedral is in the middle of The City. This masterpiece of architecture was designed by Sir Christopher Wren. The Bank of England has an interesting museum that you can visit.

Also in the the City is a very tall building - 60.6 metres high - called The Monument. Christopher Wren built this, too, and it stands on the place where the Fire of London began in 1666.

The Tower of London which is situated in the City, is now a museum, and one of London's most famous buildings. More than two million people visit it every year. You can see the Crown Jewels, and visit the Bloody Tower and the White Tower. Or take a walk round the wall and perhaps see one of the Tower's famous black birds: the ravens.

Tower Bridge is near the Tower of London. It is one of the most famous bridges in the city and first opened in 1894.

When you are tired of looking at buildings, you can sit or walk in one of London's beautiful parks.

Hyde Park has a lake in the middle called the Serpentine, and you can take a boat out on the water. It is a good place to get away from the crowds and the noise of the city. You can listen to the speakers at Speakers' Corner near Marble Arch. People from all over the world come and speak here. You can ask a speaker some difficult questions if you like. Or you can stand on a box and speak to some of the listeners!
