{{short description|Embankment built in the shape of a circle}} [[File:Ringwall von Burg Rekonstr.jpg|thumb|Artist's impression of the circular rampart of Burg, near Celle, Germany]] A '''circular rampart''' ({{Langx|de|Ringwall}})<ref>Comité International d'Histoire de l'Art (1996) ''Burgen und Feste Plätze/Chateaux-forts et places fortes/Castles and Fortified Places'', Munich: De Gruyter, p. 236.</ref> is an embankment built in the shape of a circle that was used as part of the defences for a military fortification, hill fort or refuge, or was built for religious purposes or as a place of gathering.
The period during which these structures were built ranged from the Neolithic to the Middle Ages.
==Construction== [[File:VarbolaRuins.jpg|thumb|Varbola ruins in Estonia]] The key feature of a circular rampart is that the embankment formed the primary element of the defensive fortification.<ref name= Radig>Radig (1935), pp. 9–10.</ref> It can be constructed in various ways: as a simple earth embankment, as a wood and earth structure, or as a wall. Circular ramparts usually have a moat or ditch in front of them; the embankment can be enhanced with a wooden palisade. They are mostly found on lowlands, but sometimes encircle the summit of a hill.<ref name= Radig/> Often several concentric rings were built, which produced a more effective defensive position against attackers.<ref name= Radig/> The interior of such sites often shows evidence of buildings such as halls, barns, and other secondary structures.
