Jordbro Grave Field, Iron Age burial ground in Haninge Municipality, Sweden

Jordbro Grave Field covers about 800 ancient monuments from 500 BC to 500 AD, including roughly 300 stone settings, 42 cross-shaped stone circles, two stone ships, about 300 raised stones and several sunken lanes. The Nynäs Line cuts through the field, which is about 500 metres long and 300 metres wide; a walking tunnel under the tracks at Björklund farm links the two halves.

The burial ground was used from the 5th century BC to the 5th century AD during the Iron Age. The variety of grave forms and their development across this long period shows how burial practices changed in the region over time.

The graves show how people here buried their dead and what objects they placed with them for the afterlife. You can see different types of burial markers scattered across the landscape, from circular stone arrangements to stone formations shaped like ships.

There is a small parking area at the north entrance where you can leave your car and access the forest area. Marked trails and information signs guide you through the site, making it easy to explore the different graves and monuments at your own pace.

The 1993–1994 double-tracking of the Nynäs Line led to excavations that stripped humus on the west side and exposed many previously hidden stone settings, increasing the number of visible graves by 300%. A small excavation in a sandy railway embankment also revealed traces of a Stone Age hut.
