The world-known clock. Everyday about 500 tourists come to London to see the Big Ben. Built in 1858, it was named after an architect whose name was Ben (Benjamin). The interesting fact is that you are not allowed to get inside the Big Ben if you aren’t an Englishman. No tourists allowed. 2. Madam Tussaud's Museum The most famous museum of waxworks. It presents all famous people from singers and actors to Prime Ministers and Presidents. All the waxworks are of such a good quality, that sometimes you can mistake them for a real person. 3. Piccadilly Circus. The place is far from what is called “a circus”. It is a well-known meeting point of the city. It has become so popular, that is now considered to be a place to visit for all the tourists. 4. London Eye. It is one of the biggest observation wheels in the world. Its height is 135 meters. It has 32 cabins which symbolize 32 districts of London. It takes 30 minutes to make a full circle. But it is the view you will never forget. The cost is about £20. 5. London National Gallery. The gallery has more than 2000 works of world-known artists of XIII-XX centuries. You can spend the whole day there and it will not be enough. What is interesting, is that the gallery is free for everyone.
