Götavirke

Götavirke (Geatish Dyke) are the remains of two parallel defensive walls going from north to south between the villages of Västra Husby (58°29′N 16°10′E / 58.483°N 16.167°E / 58.483; 16.167) and Hylinge (58°28′N 16°10′E / 58.467°N 16.167°E / 58.467; 16.167) in Söderköping Municipality, Östergötland, Sweden.

North of Asplången there are remains of several ancient hill forts that may have been part of the defensive line.

The walls seem to be constructed to protect the Geatish heartland around today's Linköping from attacks from the Baltic Sea.

Defence constructions were also built along the 20-kilometre narrow inlet Slätbaken that stretches from the Baltic Sea to Götavirke, and even pass it during the Viking Age when the water level was 1.5 metres higher.

[1] The wall supported a wooden pale, and behind it are traces of a military road, which makes it similar to the Danevirke protecting the contemporary town of Hedeby.

Remains of Götavirke at the farm of Hageby, in Östergötland . On the image the remains of the dyke run from the bottom right up towards the trees, and parallel with the road
