For a century, archeologists have been looking for a gate through a wall built by the Vikings in northern Europe. This summer, it was found. Researchers now believe the extensive barrier was built to protect an important trading route.
Their attacks out of nowhere in rapid longboats have led many to call Vikings the inventors of the Blitzkrieg. "Like wild hornets," reads an ancient description, the Vikings would plunder monasteries and entire cities from Ireland to Spain. The fact that the Vikings, who have since found their place as droll comic book characters, were also avid masons is slightly less well known.
The proof can be seen in northern Germany, not far from the North Sea-Baltic Canal. There, one can marvel at a giant, 30-kilometer (19-mile) wall which runs through the entire state of Schleswig-Holstein. The massive construction, called the Danevirke -- "work of the Danes" -- is considered the largest earthwork in northern Europe.
Archeologists have now taken a closer look at part of the construction -- a three-meter-thick (10 feet) wall from the 8th century near Hedeby (known as Haithabu in German). It is constructed entirely out of stones collected from the surrounding region. Some of them are only as big as a fist, while others weigh as much as 100 kilograms (220 pounds). "The Vikings collected millions of rocks," says archeologist Astrid Tummuscheit, who works for the state archeology office of Schleswig-Holstein.
