Gautavík is a well-known archaeological site on the east coast of Iceland. It was partially excavated in 1979 and interpreted as a seasonal occupied trading site, abandoned shortly after c. 1500. However, recent archaeological research on the  excavated ceramics, which hitherto had not been studied in detail, raised doubts about the interpretation regarding the dating and function of the site. New research was then initiated that included an investigation of written documents in the archives of Bremen, Hamburg, and Copenhagen, pertaining to the trade with Iceland during the sixteenth century. On the basis of the new results presented here we now interpret Gautavík to have been a trading harbour that also included a farm, at least periodically, occupied from the late twelfth century, at the latest, until shortly before 1600. Gautavík was a place of supra-regional importance, being the main port of entry in Berufjörður during the medieval period. In the sixteenth century, however, Gautavík lost its importance. This was a period of intensive trade of German merchants with Iceland, and after Bremen and Hamburg merchants established Djúpivogur and Fýluvogur at the entrance of the fjord c. 1570, both gradually superseded Gautavík, such that shortly before 1600 trade was no longer conducted there.

Viabundus is an open access online interactive map and database on roads and mobility in premodern northern and central Europe. The database covers the period 1350–1650. It is designed as a network model and includes digital reconstructions of long-distance land routes and inland waterways as well as a database with information about settlements, towns, toll stations, staple markets, fairs, bridges, ferries, harbours and shipping locks. This makes it possible to use the dataset for advanced analyses with methods of gis and network analysis. With the web application and downloadable dataset, the Viabundus project has created a tool for the analysis of premodern mobility for economic (transaction costs) and all other kinds of historical study involving movement of people and goods.

The premodern European transport network was accompanied by a number of institutions that affected the transaction costs related to commercial travel, such as fairs, staple markets and toll stations. With digital techniques and big datasets, it is now possible to study these phenomena on a grand scale and to reveal patterns in supraregional economic exchange. Using the Viabundus dataset on premodern transport and mobility in northern Europe (13501650), this article explores the possibilities that such data offer for understanding large-scale economic activity. By employing GIS mapping for visualisation purposes and methods of network analysis such as the calculation of betweenness centrality, the data on fairs, staple markets and toll stations can help us understand the institutional structure of the premodern economy in which merchants operated.
