Here we visited the Northern Port of Moscow. The two exhibits are actually located in Severnoye Park, Tushino district, Moscow and within the Museum-memorial complex of the history of the Russian Navy (Muzeyno-memorialnyy kompleks istorii VMF Rossii).
Across the river Volga from the park is the Northern Port Terminal. Back in 1997 I was on one of those river cruise ships whilst in Moscow and then went up the Volga to St. Petersburg.
