Russian President Vladimir Putin has traveled in a research submersible to the site of a 19th-century shipwreck in the Gulf of Finland.
Putin made the journey during a visit on July 15 to a Russian Geographical Society project on Gogland Island, about 180 kilometers west of St. Petersburg.
State television showed Putin visiting the wreck of the "Oleg," a warship that collided with another vessel during maneuvers and sank in 1869.
He reportedly traveled to a depth of around 60 meters.
Putin later expressed support for the idea of setting up a permanent Geographical Society base on the island.
In 2009, Putin rode a submersible to the bottom of Siberia's Lake Baikal.
In 2011, he purportedly found two Greek urns while scuba diving in the Black Sea. His office later admitted that the "discovery" was faked.
