The Peter and Paul Fortress is an absolute must-see when in Saint Petersburg. It is from here that the history of the city started back in 1703. Initially functioning as a citadel, it is now one of the main city symbols and tourist attractions.
The fortress is located on Hare Island (which is actually a peninsula) across the Neva River from Hermitage and Nevsky Prospekt. The nearest metro station is Gorkovskaya. The access to the area is via a bridge — as you walk along it, spot the statue of hare on a log in the water.
The major highlight of the place is no doubt the Peter and Paul Cathedral. With its 123-meter bell tower crowned with an angel, it is the world’s tallest Orthodox church. It is also the burial place of the Romanov family, housing imperial tombs of czars from Peter I to Nikolay II. This fact alone attracts visitors from all over the world. Impressive enough outside, inside the cathedral is plain gorgeous!
There is also a number of other historic buildings on the territory that are now turned into museums. They include the Commandant's House, now a part of the State Museum of the History of St. Petersburg, the Museum of Cosmonautics boasting actual space hardware, and some more. However, the most prominent of the museums is Trubetskoy Bastion — the former main political prison of Czarist Russia.
