Shlisselburg previously Nut, was founded in 1323 by Novgorod on the island at the source of the Neva River from Lake Ladoga. In 1352 Novgorod put "hail stone nut" with walls built of boulders (remnants of the wall can be seen in the center of a modern fortress). At the turn of the XV-XVI centuries Nut transformed into a fortress classic, designed for perimeter defense with all known types of firearms: new walls were almost at the water, not allowing the army to line up for the assault. In the years 1617-1702 the fortress was renamed in Noteburg (NUT-town), belonged to the Swedes, while the army of Boris Sheremetev not captured them after a 10-day bombardment and a severe storm. Tsar Peter I participated in the battles as a scorer, captain and wrote from there: "exceedingly tough nut this was, however, thank God, happily gnawing." It was the first major success in the Russian Northern War, and the fortress was renamed Shlisselburg (key-city). In XVIII-XIX centuries gained fame Shlisselburg "Russian Bastille": its walls were imprisoned members of the royal family (wife of Peter I Evdokia Lopukhin, legitimate king John VI Antonovich, the king's favorites, the dissenters, the Decembrists, the People, members of the Polish uprising). They were kept in the Secret House and the New Prison, where now there are museum exhibits devoted to prisoners. In the days of the Leningrad siege castle was once again at the forefront of the defense and was never taken by the Germans, covering a road of life.

Despite the insularity of the fortress, to get there easily enough from the city Shlisselburg, from the granite embankment at the mouth of the channel time of Peter the Staraya Ladoga regularly go there boats. The castle held a very informative tour (also included in the admission fee). In the summer, while on the island, you can swim in the river Neva, to feel the full force of its flow.
