Krasnaya Gorka is a Russian coastal artillery fortress on the southern shore of the Gulf of Finland, opposite Kotlin Island and the Baltic Fleet's base at Kronstadt. Nowadays, the partially abandoned Krasnaya Gorka Fort is one of the most interesting memorials of the Kronstadt Fortress and Russian naval glory.

All continents and countries with access to the sea have always had naval fortresses. Being both a country and a continent, Australia is no exception. To build a system of coastal defenses, the colonial administration invited British royal engineers. Fort Lytton was built in two years.

The Russians are here to stay — that was the motto of the Russian engineers who designed the Vladivostok Fortress. It includes two turret mounts taken from battleship Poltava. The turret — weighing 900 tons — can be rotated manually, you only need ten men for this. A coastal fortress that didn't fire a single shot in a war — because the enemy would not dare to attack it.

The Kronschlot fort was a fortress designed to be the “lock on the doors to Saint Petersburg” and protect the budding city from the enemy from the sea. The place for the fort was picked by Peter the Great personally, and the construction of the fortress was under his vigilant control. Peter the Great strategic plan proved to be a very long-term one.

From the 1920s, San Francisco was protected by two two-gun batteries, north and south of the Golden Gate strait. Throughout the duration of World War II, 150 artillerymen were living on the premises in constant combat readiness: when the alarm was sounded they had five minutes to prepare and make the shot.
