Fort Zverev, located on the shores of the Baltic Sea in northern Kronstadt, lies in complete ruins today. One of the several forts of Kronstadt, Fort Zverev was built in the 1860s by the engineer Konstantin Zverev, after which the fort is named, in order to strengthen the northern fairway of Gulf of Finland. The fort had a mushroom shape with curved ceiling, a new design different from all Konstantin Zverev had built before. In fact, it was Zverev who for the first time in Russia had successfully applied asphalt as a building material, covering the floors with natural asphalt solution.

At the beginning of the 20th century the fort was converted into a warehouse of sea mines and ammunition dump, and continued to remain on duty long after World War II ended, as a site for military training and practical shooting.
