The Norwegian Pirate Boat Museum is located on the beautiful Berg Peninsula on the southwest outskirts of Oslo and is one of the most popular tourist attractions, showing the three pirate ships that have been retained. The three vessels, unearthed in the past 100 years at the cemetery near the Oslo fjord, were vessels of the nineth to eleventh centuries where Christianity had not yet spread, and were carried by pirates in the North Sea and the Mediterranean Sea, with exquisite carvings on their hulls. The hull's streamlined appearance makes us marvel.
