Fort Konstantin

A fort you can drive to — part of the ring that was never breached.
Fort Konstantin is one of the few that can be reached by land, via the dam. The naval fortress of Kronstadt was built from 1704 until the First World War: for more than two centuries cannons and walls competed here, and throughout that time the defense of St. Petersburg from the sea was never breached. Now most of the forts are abandoned and rapidly decaying, while Konstantin is open to visitors. From here, in clear weather, you can see the chain of forts stretching toward St. Petersburg.
Tip: The wind here is strong — take a warm jacket even in summer. On the western tip of Kotlin Island is the new Ostrov Fortov (Fort Island) park with a view of the forts; in season there are boat trips.

⚓ Kronstadt: zero elevation, cast-iron pavement and the Plague Fort
A naval fortress on an island: the Naval Cathedral, the only cast-iron pavement, the booth from which Elbrus is measured, the garden of the discoverer of Antarctica and forts in the sea.
