Siuron linnavuori

The defensive structure extends several hundred meters along the northern cliff, featuring stone foundations that once supported wooden fortification walls.

Archaeological investigations of the site began in 1882, revealing evidence of ancient settlements and defensive structures from the Iron Age period.

The name Pirunportinauke, meaning Devil's Gate Gap, marks the passage between northern and southern cliffs, reflecting medieval Christian influences.

Access to the archaeological site is now primarily from the western side, as the eastern route was altered during industrial development.

The forest surrounding the hillfort contains old-growth trees, hosting specialized bird species like crested tits and tree creepers.
