Saint Petersburg (used to known as Petrograd and Leningrad) was founded by Peter the Great in 1703. Today, it’s the second biggest Russian city (after Moscow).
Saint Petersburg is a great tourist attraction. It has a lovely historic center, wonderful museum the Hermitage and many many bridges (more than in Venice). 😉
Saint Petersburg is a very popular destination in summer because of “white nights” (=long daylight). Of course, there are many places that are located quite far to north and you can experience there this phenomena; but Saint Petersburg is somehow famous because of white nights. 🙂
