1,300 years ago, a tribe of warriors tried in vain to defend a fort below Abbey Craig in Stirling, Scotland. Their failure led to the total destruction, or vitrification, of the fort by fire. Recently archaeologists spent four days investigating the site.
"Scotland has more known vitrified forts than anywhere else in Europe and here in Stirling we have our own that reflects our warlike past," said Stirling Council archaeologist Murray Cook.
The dig lasted four days.
