Fort Ino or Fort Nikolaevsky ( or форт Николаевский) is an abandoned early 20th-century Russian coastal fortification situated on the northern shore of Neva Bay in the Gulf of Finland. The fort is close to the present-day settlement Privetninskoye (Former name was Ino before 1946) of Vyborgsky District of Leningrad Oblast, opposite the Krasnaya Gorka fort on the southern shore. Fort Ino is still under Russian control. The ruins of the fortress, with an extensive system of underground tunnels, are now abandoned and are partially accessible to the public.
