Gribshunden

History

The first known mention of the ship is in a letter, dated May 16, 1486, in which John, King of Denmark, wrote "in navi nostra Griffone", Latin for "in our ship Griffon". Gribshunden and its variant names were then subsequently recorded in the Danish fleet's ship lists from 1487 to 1495.

In summer 1495, John set sail for Kalmar, Sweden, to enter into negotiations with Sten Sture the Elder, the Swedish leader who was threatening to break the Swedes away from the Kalmar Union. As the premier ship of the Danish fleet, Gribshunden was a symbol of military power intended to help deter the Swedes from independence.

However, on the way to Kalmar, while anchored in the Baltic Sea at the natural harbor near the port of Ronneby, Sweden, Gribshunden caught fire. This event was recorded in the contemporaneous Swedish Sturekronikan (Sture Chronicle) and in two German sources, Reimar Koch's Lübeck Chronicle and Caspar Weinreich's Danzig Chronicle. John himself was not aboard at the time, but, as reported by expedition member Tyge Krabbe, many of the 150 crewmen who were on the ship died as it sank. With Gribshunden lost, John was forced to cancel the expedition to Kalmar, leaving the status of the Kalmar Union in limbo for the next two years until the 1497 Battle of Rotebro, wherein the Union was reaffirmed by John's victory and Sten's defeat.

The wreck

In the 1970s, the local diving club found the wreck at a depth of 10 m (33 ft), in the southwestern Baltic Sea north of Stora Ekön (English: "Great Oak Island"), an island in the Blekinge archipelago off the coast of Ronneby in southeastern Sweden. Unaware of the identity and significance of the wreck, the divers did not tell archaeologists about the discovery until 2000; the first archaeological investigations followed in 2001 and 2002. In 2013, archaeologists identified the ship as Gribshunden through such techniques as dendrochronological sampling of the ship's timbers, which showed that they came from oak trees felled in the winter of 1482–1483.

The wooden ship is in remarkably good condition and is among the best-preserved ships from the late medieval period. That the wreckage has been left relatively free of sea worm damage has been attributed to the brackishness of the waters.

The ship is also significant for being carvel-built, the oldest such found in Nordic waters, which were at the time dominated by clinker-built ships. Surveys of the wreck indicate the ship had a length of 35 m (115 ft) and a beam of 7.5 m (25 ft). The keel is oriented northeast to southwest.

Among the artifacts found in the wreckage are chain mail, bones, barrels, glass, and capstans. The shipwreck remains loaded with artillery consisting of iron cannons, of which 11 mountings have been counted.

In August 2015, the ship attracted international media attention when a near perfectly-preserved wooden figurehead, weighing about 250 kg (551 lb), of a mythical beast was recovered from the stem and brought to the surface. Suggestive of the ship's Gribshunden ("Griffin-Hound") name, the chimeric figurehead is described as a dog-like or dragon-like sea monster with lion ears, devouring a person in its crocodilian mouth.
