Truso

Truso was a Viking Age port of trade (emporium) set up by the Scandinavians at the banks of the Nogat delta branch of the Vistula River, close to a bay (the modern Drużno lake), where it emptied into the shallow and brackish Vistula Lagoon. This sizeable lagoon is separated from the Gdańsk Bay by the Vistula Spit at the southern Baltic Sea coast. In the 9th century, the merchant Wulfstan of Hedeby travelled to Truso in the service of the English King Alfred the Great and wrote his account of the place at a prominent location of the Amber Road, which attracted merchants from central and southern Europe, who supplied the markets in the Mediterranean and the Middle East with the highly valued commodity.

The account of the voyage to the town of Truso in the land of the Pruzzens around the year 890 by Wulfstan of Hedeby has been included in Alfred the Great's translation of Orosius' Histories. Moreover, Wulfstan named Truso as being near Estmere (which is his rendition of the Old Prussian Aīstinmari and Lithuanian Aistmarės for Vistula Lagoon). In the words of Marija Gimbutas, "the name of the town is the earliest known historically in the Baltic Sea area".
