The Museum of Cultural History in Oslo recently announced that they had found the world's oldest rune stone during an excavation in 2021.

The roughly 1,800-2,000-year-old stone is called the Svingerud stone, and was found during an excavation of several grave fields near Tyrifjord, west of Oslo. The stone's name comes from this location.

“It is surprising that there are so many inscriptions on such an old stone, and there are also traces of shallow inscriptions in the Svingerud stone,” said Kristel Zilmer to sciencenorway.no. Zilmer is Professor of Written Culture and Iconography at the Museum of Cultural History (KHM).
