An emporium (plural: emporia) was one of the trading settlements that emerged in Northwestern Europe in the 6th to the 7th centuries and persisted into the 9th century. Also known in English as wics, they were characterised by their peripheral locations, usually on the shore at the edge of a kingdom, their lack of infrastructure (containing no churches) and their short-lived nature. By 1000, the emporia had been replaced by the revival of European towns. Examples include Dorestad, Quentovic, Gipeswic, Hamwic, and Lundenwic (for which see Anglo-Saxon London) at the North Sea, as well as Haithabu, Jumne and Truso on the Baltic Sea. Their role in the economic history of Western Europe remains debated^[how?]. Their most famous exponent has been the British archaeologist Richard Hodges.
