Laying on the muddy floor of the frigid inland Baltic Sea, scientists have found an almost perfectly preserved and intact shipwreck, undisturbed for hundreds of years.
Based on its incredible preservation, archaeologists have been able to date the ship back to the Renaissance. That's around the late 15th or early 16th century CE, the time of Christopher Columbus and Leonardo da Vinci.
The precise origin of the ship is unknown. It's from a time before naming ships was common; for now, it's been labelled Okänt Skepp- "Unknown Ship" in Swedish.
"Still on the main deck is an incredibly rare find - the tender boat, used to ferry crew to and from the ship, leaning against the main mast. It's a truly astonishing sight."
