It is thought to be the largest grave field dating from the Iron Age in the Nordic countries.
When Nynäsbanan was expanded to double tracks from 1993–1994, some additional excavations were done at the grave field.
On the western side of the railroad, archaeologists excavated the outer layer of humus and thus made several stone circles visible.
To the east of the railroad, stone circles are not as visible – many of them only hinted at through observation of the raised parts of the ground however, there are more erected menhirs, rectangular stone circles and grave cairns here in the eastern area of the grave field.
A smaller excavation was also done in a sandy part of the embankment by the railroad and the northern area of the grave field east of the track.
