Stevns – Home of Hrodgar and Heorot?

Stevns is a peninsula in South Eastern Zeeland in Denmark. Flat, although it raises towards the east, where it breaks into the sea in the form of high cliffs, it has recently been suggested as the location for Heorot, the hall of Hrodgar, and the home of Grendel. What did it look like in the 6th to 10th century?
