I'm in London with my classmates. We are having a grat time. Lots to see and to visit in London! Let me tell you about our stay here.

On Manday, we visited the Tower of London and spent the whole day there. I took lots of photos. Next to the Tower there's the famous Tower Bridge.

I was lucky to get photos of Tower Bridge when it was open, wasn't i? I'll show you sometime. Next day we want to Buckingham Palace and saw the Changing of the Guard. There were a lot of tourists there. Imagine, there ate more than 600 rooms in the  palace and the royal family has got a cinema and a swimmming pool there.

We spent Wednesday in Greenwich. We went there on a boat. We visited the home of the "Prime Meridian", the imaginary line that divides the world into east and west. Fantastic place!

Yasterday it was rainy and windy, so we went to the British Museum. You collect coins, don't you? I bought a special souvenir for you there. Hope you'll like it. Today it's sunny and warm, and we are going to the London Eye.

Well. I must go now. It's time to leave.
