Location of Heorot
Modern scholarship sees the village of Lejre, near Roskilde, as the location of Heorot. In Scandinavian sources, Heorot corresponds to Hleiðargarðr, King Hroðulf's (Hrólfr Kraki) hall mentioned in Hrólf Kraki's saga, and located in Lejre. The medieval chroniclers Saxo Grammaticus and Sven Aggesen already suggested that Lejre was the chief residence of Hroðgar's Skjöldung clan (called "Scylding" in the poem). The remains of a Viking hall complex was uncovered southwest of Lejre in 1986-88 by Tom Christensen of the Roskilde Museum. Wood from the foundation was radiocarbon-dated to about 880. It was later found that this hall was built over an older hall which has been dated to 680. In 2004-05, Christensen excavated a third hall located just north of the other two. This hall was built in the mid-6th century, all three halls were about 50 meters long.
Fred C. Robinson is also convinced by this identification: "Hrothgar (and later Hrothulf) ruled from a royal settlement whose present location can with fair confidence be fixed as the modern Danish village of Leire, the actual location of Heorot. The most recent publication on Lejre and its role in Beowulf is by Marijane Osborn and John Niles, Beowulf and Lejre.
