Shlisselburg Fortress, located in Shlisselburg, Russia, is a historically significant structure situated on Orekhovy Island in Lake Ladoga. Founded in 1323, the fortress originally served as a strategic defense point controlling access to the Neva River and protecting the approaches to Novgorod and later Saint Petersburg. Over the centuries, it has witnessed numerous battles and sieges, most notably during the Great Northern War when it was captured by Peter the Great in 1702. The fortress also functioned as a notorious prison, housing prominent political prisoners such as Ivan VI and members of the Decembrist revolt.
