It is of special importance in Central European prehistory because of the sequence of collective burial layers contained within it.
The tomb, or gallery grave, is located on a slight rise near the village of Niedertiefenbach, about 2 km north of the river Lahn.
The tomb belongs to the Hessian-Westphalian stone cist group (Hessisch-Westfälische Steinkistengruppe), which is part of the Wartberg culture.
The relatively large gaps between the slabs were filled with drystone walling (a feature well known from gallery graves elsewhere in Europe, but not familiar within the Lahn and Kassel basin groups of tombs).
Its height can be determined, as the tops of the orthostaths had not been destroyed by ploughing; it was low, at 0.8 to 0.88 m.[4] In 1859, one slab remained of the ceiling.
It is doubtful whether the bodies entered the tomb through its entrance, as the uppermost levels of burials are only 30 cm under the top of the orthostaths.
Layer 10 had two articulated skeletons, lying on their back with their arms crossed on the chest, at right angles to the chamber.
Layer 8 contained three badly preserved, but articulate, skeletons, this time parallel to the chamber, again with the arms crossed over the body.
Layer 1, the top of the burial deposit, had a mixture of short and long bones spread all over the excavated area, as well as more than fifteen skulls.
The males had an average height of 1.68 m, the females of 1.53 m. One adult, and one young child, displayed signs of violent injury with a tool.
[15] The presence of several copper ornaments probably places phases 2 and 3 of the Niedertiefenbach tomb, but not necessarily its erection, in late Wartberg, after 3000 BC.
[2] Immel et al. 2019 examined the remains of 42 people of the Wartberg culture buried at Niedertiefenbach c. 3300-3200 BC.
The predominance of the single Y-DNA lineage indicated that the people buried at Niedertiefenbach belonged to a patrilineal society.
