Götavirke ("Geatish Dyke") are the remains of two parallel defensive walls going from north to south between the villages of Västra Husby (coord|58|29|N|16|10|E|) and Hylinge (coord|58|28|N|16|10|E|) in
Östergötland, Sweden. The walls cover the distance between the lakes Asplången (coord|58|30|N|16|08|E|) and Lillsjön (coord|58|28|N|16|10|E|). North of Asplången there are remains of several ancient hill forts that may have been part of the defensive line. South of Lake Lillsjön, the terrain is so hard to pass that it hardly needed any defenses.
The walls seem to be constructed to protect the
Geatish heartland around today's Linköpingfrom attacks from the Baltic Sea. Archaeological excavations have shown that the walls were constructed ca 800. Defense constructions were also built along the 20-kilometer narrow inlet Slätbakenthat stretches from the Baltic Sea to Götavirke, and even pass it during the Viking Age when the water level was 1.5 meters higher. The measures that Geats had taken to protect the route have no match in the Viking Age Sweden. [Anders Högmer, Arkeologiskt kontaktseminarium, Jyllands Rømø 1994. Published in "Marinarkeologi 1998".

The wall supported a wooden pale and behind it are traces of a military road, which makes it similar to
Danevirkeprotecting the contemporary town of Hedeby. No Viking Age towns are however known in the vicinity of Götavirke.
