My first visit to London was one and a half years ago. It was a wonderful trip. I stayed in the city for three weeks, and I had many impressions. I visited all the famous places. I'd like to tell you about some of the places I visited in this beautiful city. First, I went to the Tower of London, and I want to say that it is a very interesting historical place. I found out that a long time ago, it was a prison. Later it became a castle for the royal  family. Or maybe it is the reverse; I'm not sure, but later they left this place and lived in Buckingham Palace and Kensington Palace. I also enjoyed visiting the House of Parliament and Westminster Abbey, two very popular places for tourists. They are very old and beautiful. The Abbey is built in a kind of Gothic style; it is fantastic. In London, you can also enjoy nature. There are many parks such as Hyde Park, Green Park, and Holland Park. These parks are wonderful green, quiet places where you can relax and escape the noise of the city. Trafalgar Square is a popular place for students and other young people. You will find lots of pigeons  there. If you have time, you can feed them and they will be very happy. You can buy special food for them, but be careful! Tons of birds are going to surround you if you feed them. Another very special place in London that I like is St. Paul's Cathedral which was designed by Sir Christopher Wren. I also was impressed with the museums in London. They're very popular. I found them interesting because you can learn about the history of England. I had a wonderful time in London. I really liked it because it is a city that is rich in history. The writer writes this passage to  _  .
