Peter I

Peter I is a naval fortress built on an artificial island in the Gulf of Finland, located about 4 kilometers from Kronstadt. The structure features thick defensive walls, gun emplacements, and artillery batteries positioned to control the sea approach.

The fortress was founded in 1721 as part of a construction program to strengthen Russian control over the Baltic Sea. It formed part of a network of island forts that together protected the strategic harbor of Kronstadt and the approaches to the Gulf of Finland.

The fortress served as a symbol of Russian naval power and continues to define the character of Kronstadt's island landscape. Today visitors can see the cannons and stone defensive walls that speak to its military importance.

Access is available only through organized tours departing from Kronstadt by boat across the water. Sturdy footwear and weatherproof clothing are recommended, as the island tends to be windy and often damp.

The island itself is not natural but was artificially created and reinforced with stone to support the fortress. This engineering project was a remarkable feat for its time, showing how critical the location was to Russian strategy.
