This is the stern of the Vasa, It rolled over on it's maiden voyage, which lasted about 1/4 mile. The cause for the roll over was not enough ballast. She remained "lost:" until it was found 333 years later. It is more than 90% intact and now, after preservation, on display at it's permanent museum. A Must see for anyone coming to Stockholm... Arrive Early as the line gets LONG in a hurry.
