Circular rampart

A circular rampart (Ringwall) 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. The key feature of a circular rampart is that the embankment formed the primary element of the defensive fortification. 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. Often several concentric rings were built, which produced a more effective defensive position against attackers. The interior of such sites often shows evidence of buildings such as halls, barns, and other secondary structures. Circular ramparts are found in north and western Europe, for example, in Denmark, Estonia, Sweden, Germany, Great Britain, Belgium and the Netherlands; in central Europe, in Austria and Switzerland; in southeastern Europe in Romania, Moldova and Ukraine; and also in the United States. They are often hidden in woods and discovered by aerial photography. Archaeological profiles through the defences and excavations of the interior enable analysis of the period the site was occupied, the pottery used and the type of food consumed.

Viking ring fortress

A Viking ring fortress, or Trelleborg-type fortress, is a type of circular fort of a special design, built in Scandinavia during the Viking Age. Collectively, they may also be known as trelleborgs. These fortresses have a strictly circular shape, with roads and gates pointing in the four cardinal directions. They are sometimes partially encircled by advanced ramparts, though not always circular. There are a total of seven known Viking ring fortresses at present, located in Denmark and Scania, Sweden.

Ringfort

Ringforts, ring forts or ring fortresses are circular fortified settlements that were mostly built during the Bronze Age up to about the year 1000. They are found in Northern Europe, especially in Ireland. There are also many in South Wales and in Cornwall, where they are called rounds. Ringforts come in many sizes and may be made of stone or earth. Earthen ringforts would have been marked by a circular rampart (a bank and ditch), often with a stakewall. Both stone and earthen ringforts would generally have had at least one building inside.

Oppidum

An oppidum (plural oppida) is a large fortified Iron Age settlement or town. Oppida are primarily associated with the Celtic late La Tène culture, emerging during the 2nd and 1st centuries BC, spread across Europe, stretching from Britain and Iberia in the west to the edge of the Hungarian plain in the east. These settlements continued to be used until the Romans conquered Southern and Western Europe. Many subsequently became Roman-era towns and cities, whilst others were abandoned.
