The Viking Age c. 750–1050 was an era when huge quantities of iron were produced. The simple question how this iron found its way from the production sites out into the wider Viking society is easy to pose, but difficult to answer. To demonstrate how the iron bars through exchange, middle-men and various markets reached the customers is demanding from an archaeological perspective. Furthermore, written contemporaneous sources are lacking, both in Scandinavia and on the Continent. The social structure of the period, and the traditions of the various networks that transported the iron, as well as the rise and fall of harbour sites, central places and early towns add to the complexity. Even harder is trying estimate the demand of iron from abroad. However, through various archaeological materials and sites there are indications, although not full answers to the question. This paper will discuss some of these as well as give a historical background.
