Aska barrow identified as possible Viking feasting hall

What was long identified as a burial mound near Vadstena, Sweden has been determined to be a huge building, probably a feasting hall, measuring almost 50 metres in length.

The discovery was made using ground-penetrating radar by a team from the Archaeological Research Laboratory at Stockholm University. The Aska barrow, where the foundations of the hall were found, is located near a Viking Period burial site where royal graves were discovered, leading experts to believe that the building might be a royal hall.
