When archaeologists were excavating a dry prehistoric lake bed in Motala, Sweden in 2009, they stumbled upon one of the most peculiar archaeological discoveries the nation had seen – the so-called ‘Tomb of the Sunken Skulls’, a collection of skulls dating back 8,000 years, which had been mounted on stakes.
The Tomb of the Sunken Skulls is located on the eastern shore of Lake Vättern in the south eastern corner of Sweden. In 2009, a new railway line was to be built over a site known as Kanaljorden, where there once was a shallow lake. Before construction could commence, however, an excavation had to be conducted on the dry riverbed to determine if anything archaeologically important was buried beneath it. What the archaeologists found was a mysterious site dated back to Sweden’s Mesolithic period.
