1. It ts the capital of the Russian Federation. It was founded in 1147 by Prince Yuri Dolgoryky. Now it's a modern city. It is one of the biggest cities in Europe. A river runs through the centre of it. This wonderful Russian city is famous for its many places of interest. There are more than 80 museums, 10 large stadiums, and 40 theatres. Everyone knows Red Square and the Kremlin, the Tretyakov Gallery, the Pushkin Museum and the Bolshoi Theatre. It's city at the very heart of Russia!

2. It was founded by tsar Peter the Great in 1703. The city was the capital of Russia in the 18th to 19th centuries. It stands on the Neva River. There are many canals which divide it into islands. That's why there are so many lovely bridges in the city. There are also lots of famous museums, churches and cathedrals. The city is a real "open air museum". You can learn a lot about Russian history in this place. You'll want to visit it again and again!
