Caesar named 28 ''oppida''. By 2011, only 21 of these had been positively identified by historians and archaeologists: either there was a traceable similarity between the Latin and the modern name of the locality (e.g. Civitas Aurelianorum-

, for example, was referred to as an ''oppidum'', but no fortifications dating to this period have yet been discovered there. Caesar also refers to 20 ''oppida'' of the Bituriges and 12 of the Helvetii, twice the number of fortified settlements of these groups known today. That implies that Caesar likely counted some unfortified settlements as ''oppida''. A similar ambiguity is in evidence in writing by the Roman historian Livy, who also used the word for both fortified and unfortified settlements.

In archaeology and prehistory, the term ''oppida'' now refers to a category of settlement; it was first used in that sense by Paul Reinecke, Joseph Déchelette and in reference to Bibracte, Manching, and Závist. In particular, Dehn suggested defining an oppidum by four criteria:
# Size: The settlement has to have a minimum size, defined by Dehn as .
# Topography: Most ''oppida'' are situated on heights, but some are located on flat areas of land.
# Fortification: The settlement is surrounded by a (ideally uninterrupted) wall, usually consisting of three elements: a facade of stone, a wooden construction and an earthen rampart at the back. Gates are usually pincer gates.
# Chronology: The settlement dates from the late

s. They are often described as 'the first cities north of the Alps', though earlier examples of urbanism in temperate Europe are also known. The 2nd and 1st centuries BC places them in the period known as La Tène. A notional minimum size of has often been suggested, but that is flexible and fortified sites as small as have been described as ''oppida''. However, the term is not always rigorously used, and it has been used to refer to any hill fort or circular rampart dating from the La Tène period. One of the effects of the inconsistency in definitions is that it is uncertain how many ''oppida'' were built.
In European archaeology, the term ''oppida'' is also used more widely to characterize any fortified prehistoric settlement. For example, significantly older hill-top structures like the one at Glauberg (6th or 5th century BC) have been called ''oppida''.
Such wider use of the term is, for example, common in the Iberian archaeology; in the descriptions of the Castro culture it is commonly used to refer to the settlements going back to the 9th century BC. The Spanish word , also used in English, means 'a walled settlement' or 'hill fort', and this word is often used interchangeably with ''oppidum'' by archaeologists.
Location and type
According to pre-historian John Collis, oppida extend as far east as the Hungarian plain where other settlement types take over. Around 200 ''oppida'' are known today. Central Spain has sites similar to oppida, but while they share features such as size and defensive ramparts the interior was arranged differently. ''Oppida'' feature a wide variety of internal structures, from continuous rows of dwellings ( Bibracte) to more widely spaced individual estates ( Manching). Some ''oppida'' had internal layouts resembling the '' insulae'' of Roman cities (Variscourt). Little is known, however, about the purpose of any public buildings.
The main features of the oppida are the walls and gates, the spacious layout, and usually a commanding view of the surrounding area. The major difference with earlier structures was their much larger size. Earlier hill forts were mostly just a few hectares in area, whilst ''oppida'' could encompass several dozen or even hundreds of hectares. They also played a role in displaying the power and wealth of the local inhabitants and as a line of demarcation between the town and the countryside. According to Jane McIntosh, the "impressive ramparts with elaborate gateways ... were probably as much for show and for controlling the movement of people and goods as for defense".McIntosh (2009), p. 156 Some of the ''oppida'' fortifications were built on an immense scale. Construction of the 7km-long ' at Manching required an estimated 6,900 m3 of stones for the façade alone, up to 7.5 tons of iron nails, 90,000 m3 of earth and stones for the fill between the posts and 100,000 m3 of earth for the ramp. In terms of labour, some 2,000 people would have been needed for 250 days. The 5.5km-long of Bibracte may have required 40 to 60

were much larger than those found in the north and west of France. Typically ''oppida'' in Britain are small, but there is a group of large oppida in the south east; though oppida are uncommon in northern Britain, Stanwick stands out as an unusual example as it covers . Dry stone walls supported by a bank of earth, called Kelheim ramparts, were characteristic of oppida in central Europe. To the east, timbers were often used to support the earth and stone ramparts, called '' Pfostenschlitzmauer'' (post slot wall) or " Preist-type wall". In western Europe, especially Gaul, the '' murus gallicus'' (a timber frame nailed together, with a stone facade and earth/stone fill), was the dominant form of rampart construction. Dump ramparts, that is earth unsupported by timber, were common in Britain and were later adopted in France. They have been found in particular in the north-west and central regions of France and were combined with wide moats ("Type Fécamp"). Oppida can be divided into two broad groups, those around the Mediterranean coast and those further inland. The latter group were larger, more varied, and spaced further apart.

Published by Tempus Publishing () These earthworks are considered the most extensive of their kind in Britain, and together with the two rivers enclosed the high status farmsteads, burial grounds, religious sites, industrial areas, river port and coin mint of the Trinovantes.
History
Prehistoric Europe saw a growing population. According to Jane McIntosh, in about 5,000 BC during the Neolithic between 2 million and 5 million people lived in Europe;McIntosh (2009), p. 349 in the late (pre-Roman) Iron Age (2nd and 1st centuries BC) it had an estimated population of around 15 to 30 million. Outside Greece and Italy, which were more densely populated, the vast majority of settlements in the Iron Age were small, with perhaps no more than 50 inhabitants. While hill forts could accommodate up to 1,000 people, ''oppida'' in the late Iron Age could reach as large as 10,000 inhabitants.
''Oppida'' originated in the 2nd and 1st centuries BC. Most were built on fresh sites, usually on an elevated position. Such a location would have allowed the settlement to dominate nearby trade routes and may also have been important as a symbol of control of the area. For instance at the ''oppidum'' of Ulaca in Spain the height of the ramparts is not uniform: those overlooking the valley are considerably higher than those facing towards the mountains in the area. The traditional explanation is that the smaller ramparts were unfinished because the region was invaded by the Romans; however, archaeologist John Collis dismisses this explanation because the inhabitants managed to build a second rampart extending the site by to cover an area of . Instead he believes the role of the ramparts as a status symbol may have been more important than their defensive qualities.
While some ''oppida'' grew from hill forts, by no means all of them had significant defensive functions. The development of ''oppida'' was a milestone in the urbanisation of the continent as they were among the first large settlements north of the Alps that could genuinely be described as towns or cities (earlier sites include the 'Princely Seats' of the Hallstatt period). Caesar pointed out that each tribe of Gaul would have several ''oppida'' but that they were not all of equal importance, implying a form of settlement hierarchy, with some ''oppida'' serving as regional capitals. This is also reflected in the archaeological evidence. According to Fichtl (2018), in the first century BC Gaul was divided into around sixty (the term used by Caesar) or 'autonomous city-states', which were mostly organized around one or more ''oppida''. In some cases, "one of these can be regarded effectively as a capital."
''Oppida'' continued in use until the Romans began conquering Iron Age Europe. Even in the lands north of the River Danube that remained unconquered by the Romans, ''oppida'' were abandoned by the late 1st century AD. In conquered lands, the Romans used the infrastructure of the ''oppida'' to administer the empire, and many became full Roman towns. This often involved a change of location from the hilltop into the plain.
