A major cultural and scientific center where you can see legendary exhibit ships (the research vessel Vityaz, the submarine B-413, the space communications vessel Kosmonavt Viktor Patsayev, and others), learn about the history of navigation, oceanography, and marine flora and fauna, visit an aquarium, exhibits on ocean geology, and a collection of rare artifacts, and stroll along the Peter the Great Embankment, which has been transformed into a veritable open-air museum.
