The remains of the Äskekärrsskeppet I, in Göteborgs Stadsmuseum
The Äskekärr I was found in 1933 by a farmer on a field near Äskekärr only 50m from the Göta älv river away in Sweden. She is 16m long and about 4m wide, but she is not a warship, she is a knarr, a merchant ship which is dated around 930 AD.
Her planks are made of oak with a thickness of 15 to 20 mm and are joined together with iron rivets with round heads and held inside on square iron pedestals. According to the analysis, the sealing was made of sheep's wool soaked in pitch (coniferous wood resin). Runes were found on one side of the hull (Fehu-Rune), and on some other parts (like the base of the mast). That she looks like this, is probably due to the fact that her wood was used for other purposes.
In the same year further investigations were made and besides another, but younger, wreck of a rattle, also structures with the shape of a horse shoe had been found.The site may have been a shipyard.
