A causeway the Viking Jarlabanke built in the 1000s on the road to Roslagen, still lined with rune stones from his time. Today's foot and bike path follows the original route through a rebuilt landscape of ash, rowan and a winding stream.

The Jarlabankeleken playground has a Viking ship, a climbing sculpture, swings, a sandbox and a play rune stone. Boards in the rain shelter tell the area's Viking story.
