Gulf of Peter the Great

The Peter the Great Gulf (Russian: Залив Петра Великого) is the largest gulf of the Sea of Japan adjoining the coast of Russia's Primorski Krai. The Muravyov-Amursky Peninsula and a chain of outlying islands divides the gulf of about 6,000 km² into the Amur Bay and the Ussuri Bay. Vladivostok is located there.

The Peter the Great Gulf extends for 185 km (115 mi) from the mouth of the Tumen River (on the Russian-Chinese border) northeast across to Cape Povorotny. The bay reaches inland for 90 km (56 mi). The functioning of these harbours is severely limited by the freezing of the bay from early December to mid-April. Formerly (since 1855) known as Victoria Bay, the inlet was renamed in 1859 to honour Peter I the Great.

The coastline of about 1,500 kilometers is indented by many smaller bays, the chief of which are Possiet, to the west; the Zolotoy Rog (the "Golden Horn"), Diomede and Lazurnaya (the "Shamora", with its fine sandy beaches) on the Peninsula; and Strelok, Vostok and Nakhodka to the east. The islands include the Rimsky-Korsakov Archipelago and Furugelm Island to the west, the Eugénie Archipelago (of which Russky Island is the largest), separated from the Peninsula by the Eastern Bosphorus), and Askold and Putyatin to the east.
