Mortuary complex comprising about 35 burial mounds grouped around the Hohmichele, the second largest early Iron Age round barrow in Europe, with a diameter of about 80 m and a preserved height of 13 m, associated with the Heuneburg hillfort. The Hohmichele was partially investigated by G. Riek in the 1930s and found to contain eight inhumations and five cremations. Two of the burials had wagons with them. All appeared to date to the 6th century bc. More recently, excavations directed by Bettina Arnold and Matthew L. Murray have investigated Mound 17. Before excavation this mound stood 3 m high and was about 20 m in diameter. Five individuals of above average status had been buried in the mound, starting in about 600 bc with the central cremation. A later warrior grave contained a bronze cauldron and a set of iron weapons. The last burial dated to about 450 bc.
