The location can be somewhat troublesome to find on a navigator, I recommend using the GPS coordinates that I supplied.
The address is unmarked but is located just across the road from Gl Fjellerupvej 21, 8961 Allingåbro, Denmark
Parking at the info center not far from the burial mounds
the largest passage grave in Eastern Jutland, is an example of Funnelbeaker culture circa 3200 BC. The passage tomb consists of a narrow passage made of large stones and one or multiple burial chambers covered in earth or stone. The building of passage tombs was normally carried out with megaliths and smaller stones; they usually date from the Neolithic Age.
