Lingsberg Runestones, 11th-century runestones in Vallentuna Municipality, Sweden

The Lingsberg Runestones are two 11th-century runestones, U 240 and U 241, with a fragment U 242, at Lingsberg farm about 2 km east of Vallentuna. U 240 stands at the end of a causeway facing U 241, which was found in 1909 and moved to the farm courtyard. Both are carved in Urnes style (Pr3) by Åsmund, with serpents and a cross.

The stones were created in the 11th century, and their inscriptions mention two Danegeld payments linked to military actions in England. These texts show the connection of Scandinavian warriors to events occurring in that region during this period.

The stones bear inscriptions in Old Norse using younger runes, showing how people of that era created memorial stones and the writing system they used.

U 240 stands in a field at the end of a causeway whose traces are visible; U 241 and the U 242 fragment lie in the courtyard and drive of the Lingsberg main building. The ground was marshy until Lake Angarn was lowered in the 19th century. The site is about 2 km east of Vallentuna, halfway to Kusta.

U 241 was found in 1909 while a field was being ploughed, and it now stands in the courtyard of Lingsberg's main building, with the U 242 fragment lying beside it at the drive. U 240, by contrast, remains in its field at the end of the old causeway.
