- Historical period
- c. AD 800–930, with continued activity later in the tenth century
- Site type
- Trading harbour and craft settlement
On the tranquil shores of Viksfjord, near the present-day Norwegian town of Larvik, lie the remains of one of Viking Scandinavia’s most important trading centres. Kaupang emerged around the year 800 and became a meeting place for seafarers, merchants and craftspeople from different parts of northern Europe.
Generally regarded as Norway’s earliest known urban settlement, it belonged to the network of trading centres that also included Ribe, Hedeby and Birka. Its name captures its purpose: it derives from the Old Norse word kaupangr, meaning “market” or “trading place”.
The Birth of a Viking Town
Kaupang was not a stone-built town filled with grand monuments. Its urban character lay in its concentration of homes, its organised layout and the presence of people whose livelihoods depended on trade and craft production.
The central settlement may have contained around 90–100 plots, separated by ditches and fences. Each provided enough space for a building and a small outdoor area. This arrangement reveals a recognisable pattern of organisation, comparable to that of other Viking trading centres.
At its height, Kaupang may have had 400–600 inhabitants. Although modest by modern standards, this was a significant concentration of people in a predominantly rural society. Archaeological research also distinguishes between buildings used temporarily and houses occupied permanently from the 820s onwards: the marketplace was becoming an established community.
A Port Connected to Distant Lands
The objects recovered at Kaupang reveal a remarkably extensive trading network. Frankish glass vessels, pottery from the Rhineland and the southern Baltic, and silver coins from the Islamic caliphate all reached the settlement.
Archaeologists have also found glass beads made in the Mediterranean and the Middle East, as well as carnelian beads associated with regions around the Black Sea or the Caspian Sea. This does not mean that Kaupang’s merchants travelled personally to every place represented by these finds. Many goods probably passed through several intermediaries before reaching the Norwegian port.
During its early decades, Kaupang maintained particularly strong connections with Frisia, probably including the great trading centre of Dorestad in what is now the Netherlands. These links weakened during the second half of the ninth century, while contacts with southern Scandinavia, the Baltic and the Irish Sea continued. Kaupang belonged to trading networks that shifted over time.
Silver, Weights and Everyday Exchange
Silver played a prominent role in commerce. Finds include both coins and weights, evidence of transactions in which precious metal and its measurement mattered. A coin’s value could depend on its silver content and weight, rather than simply on the authority that had issued it.
Other discoveries reveal more ordinary aspects of life: gaming pieces, fishing weights, whetstones, ornaments and household vessels. Alongside goods from distant lands are traces of people who fished, worked, played and made their homes in the settlement.
Craftspeople Who Transformed Goods
Kaupang did more than receive and redistribute merchandise. Crucibles, moulds and casting waste show that craftspeople produced jewellery and other metal objects within the settlement.
Glassworking left particularly revealing evidence. Alongside finished beads, archaeologists discovered defective examples and raw materials, indicating that some beads were made locally. Amber fragments bearing cut marks, together with unfinished beads, likewise suggest that amber was worked on site.
Loom weights and spindle whorls—tools used in weaving and spinning—also document textile production. Behind the image of a bustling harbour stood a community of skilled workers whose knowledge helped sustain its economy.
A Community of Diverse Origins
Personal possessions suggest that some inhabitants had connections with different Scandinavian regions and with Frisia. Researchers have interpreted one house as the home of a Frisian household engaged in trade.
A Slavic presence has also been proposed, although it is harder to establish whether these individuals were permanent residents. Such interpretations require care: a foreign object could arrive through trade and does not, by itself, establish its owner’s origins. Nevertheless, the finds collectively suggest a port where people with different customs and experiences encountered one another.
Skiringssal and the Power of Regional Elites
Kaupang developed within a landscape shaped by regional power. At nearby Huseby, archaeologists identified the remains of a great hall measuring approximately 33 metres long and 10 metres wide, associated with the local elite.
A building of this size offers a sense of the political importance of the surrounding area. Trade flourished close to places where leaders gathered with their associates, strengthened alliances and displayed their status. The proximity of political authority helps explain why a commercial settlement developed here.
Óttar and a Name That Still Raises Questions
Around AD 890, the Norwegian seafarer Óttar recounted his voyages at the court of King Alfred of Wessex. His account mentions a place called Sciringesheal, traditionally associated with Skiringssal and Kaupang.
The precise identification nevertheless deserves some caution. The discovery of another contemporary trading site at Heimdal, near Gokstad, has prompted reconsideration of aspects of this association. Óttar’s account remains an essential source, but connecting a name recorded more than a thousand years ago with a particular archaeological site is not always straightforward.
A Decline That Did Not Happen Overnight
Kaupang’s principal phase of permanent occupation is usually dated to approximately AD 800–930. However, 930 should not be understood as an absolute closing date: evidence suggests that some trading and craft activities continued for several decades.
The reasons for its abandonment remain uncertain. Changes in trading routes and centres of political power may have undermined its position. More recent research has also identified craft activity during a later phase, suggesting a gradual and uneven transformation rather than an abrupt disappearance.
Rediscovering a Town Beneath the Fields
Early investigations focused on the graves and burial grounds surrounding Kaupang. Nicolay Nicolaysen excavated there during the second half of the nineteenth century, long before the settlement itself was properly understood.
During the 1950s, archaeologists began identifying its residential remains. The research programme undertaken between 1998 and 2003 greatly expanded knowledge of its buildings, productive activities and commercial connections.
One particularly striking detail is that the Viking shoreline differed from today’s: the contemporary shoreline lay approximately 3.5 metres above the present one. To understand the harbour, archaeologists have therefore also had to reconstruct the landscape its inhabitants knew.
Kaupang brings the Viking Age into focus through workplaces and everyday possessions. A weight, a casting mould or an unfinished glass bead tells a story of skills, journeys and exchange: the story of a small Norwegian community connected to a much wider world.
