The United Kingdom of Great Britain
The United Kingdom of Great Britain and Northern Ireland is situated on the British Isles -Great Britain and Ireland, and about seven hundred small islands. Its population is over 67 million.
The United Kingdom is made up of four countries: England, Wales, Scotland and Northern Ireland. Their capitals are Cardiff, Edinburgh and Belfast. The capital of the UK is London.
The UK is a monarchy and Queen Elisabeth II is the official Head of the country. However, the British monarch does not have political power because Parliament makes the laws.
William is the future King of the United Kingdom. He is the Queen’s grandson and the eldest son of Charles and Diana. William and his wife Kate live in a large apartment in Kensington Palace in London with their three children. William has a lot of royal duties: he meets foreign kings, queens and presidents and he helps a lot of different charities. He is famous all around the world, but he doesn’t want to be special or different.
One of the most famous buildings in England is Buckingham Palace. When Queen is staying at the palace, you can see the flag on the roof of the building. In August and September tourists can visit some of the rooms in the palace,take photos of the palace and of the soldiers outside. London is full of museums and art galleries, theatres and clubs.
I would like to visit London because I think it is a fantastic experience. I’d like to see the Big Ben, the London Eye, Buckingham Palace, Tower Bridge and the London Zoo.
The London Eye is of the main sights of the city and over 4 million visitors come see it every year. London eye was called the Millennium wheel at first because it was open in 2000. The wheel is 135 meters high and it takes 30 minutes to complete one ride. There are 32 capsules and 25 people can fit in one of them.
The London eye can be seen from different parts of the city. At night time it’s illuminated. Tourists love taking photos of it because they come out so pretty.
