Ismantorp hill fort

The limestone fortress extends 300 meters with nine gates and contains 95 houses arranged in 12 blocks around a central circular structure.

Built around 200 CE, the fortress remained active until 650 CE, making it the oldest among the 20 ring fortresses on Öland island.

The fort layout includes gates oriented toward a central pit representing Urd's well, following Nordic beliefs about the center of the world.

Located in Mittlandskogen forest near Borgholm, the archaeological site features preserved walls reaching 4 meters in height with visible house foundations.

Archaeological studies indicate the fortress was never permanently inhabited despite its size and structural complexity, suggesting ceremonial or training purposes.
