Ärja

... Ulfr(?) raised this stone in memory of his brother Ósníkinn. He travelled to the east with Ingvarr; (he was) Holmsteinn's seaman.

This is one of many Ingvar-stones. Read more about them here. There's another one standing in Mariefred, a few kilometers away : Sö 179. Like Sö 333, you'll find this rune stone is standing by the ruins of Ärja church. Sö 334 was taken out of the wall of this church, and is now kept in Mariefred church.
