In St. Petersburg there are a lot of parks and gardens where citizens spend their free time. The Summer Garden is the oldest and most fascinating park. Rare trees, bushes and flowers grow there. Beautiful marble statues made by Italian sculptors and a famous cast iron grille decorate the Summer Garden. There is a bronze monument to the prominent Russian writer of fables Ivan Krylov (by sculptor Klodt) in the Summer Garden.
St. Petersburg is famous for its magnificent architecture of the 18th and 19th centuries. The city began with the Peter and Paul Portress built to protect the Neva banks from Swedish invasion. Later Domeniko Trezzini, the famous Swiss architect, reconstructed the fortress, It became a prison. Now it is a museum. Trezzini erected the Peter and Paul Cathedral here, and Russian tsars were buried in it.
The most famous square in the city is the Palace Square. Here one can see the Winter Palace built by Rastrelli.
