The Guardian article about Erdoğan’s Bartonesque way with history said that
Some researchers believe Vikings reached America before the end of the first millennium.
No, it’s not some and it’s not “believe” – there’s solid evidence that they did. It’s from
L’Anse aux Meadows in Newfoundland.
In the early 1960s, archaeologists Helge Ingstad and his wife Anne Stine Ingstad undertook a close survey of the coastlines of Newfoundland and Labrador. Ingstad, a Norse investigator, had spent the majority of his career studying Northern and Arctic civilizations, and was following up on research into the Viking explorations of the 10th and 11th centuries. In 1961, the survey paid off, and the Ingstads discovered an indisputably Viking settlement near Epave Bay and named the site “L’Anse aux Meadows,” or Jellyfish Cove, a reference to the stinging jellyfish found in the bay.
Eleventh century Norse artifacts recovered from l’Anse aux Meadows numbered in the hundreds, and included a soapstone spindle whorl and a bronze-ringed pin process, as well as other iron, bronze, stone, and bone items. Radiocarbon dates placed the occupation at the site between ~990-1030 AD.
It was a failed settlement, that lasted only 3 to 10 years.
