In March 2021 Norwegian archaeologists posted the photo above on Facebook, asking their followers what they thought these planks might have been used for. The planks had been found during an archaeological excavation in the centre of the Norwegian city of Trondheim in the 1980s, but nobody had ever figured out what they had been used for. The planks were thought to date to the 12th century.
