The name means Frigg's field. She was the wife of Odin, so here we've got a heathen name on one of the earliest churchplaces ! It has probably been some kind of a heathen sanctuary earlier, that got transformed into a Christian one. The ruins of the church are not from Saint Sigfrids days - more likely from the 12th century, just like Agnestad churchruin.

Not far from Friggeråker is Gudhem, with its ruins of a nunnery.
