I will tell you the history of the fortress and the foundation of the city along with some historic anecdotes.
The undefeatable Peter and Paul Fortress is located on a separate island in the heart of St. Petersburg.
The citadel has been there for over 300 years — one of the first buildings of the city constructed with the aim of defending the territory of the future capital of the Russian Empire.
The fortress contains several notable buildings clustered around the Peter and Paul Cathedral.
A Cathedral itself is a memorial to victory over Sweden in 18c. Now it is a sepulchre of the Romanov dinasty and a vibrant example of the Petrovian baroque style.
The fortress walls overlook sandy beaches that have become very popular in St. Petersburg. In summer, the beach is often overcrowded, especially when a major sand festival takes place on the shore.
That photostroll would be a great option to see the historic scenery and keep memories in photographs.
