Poet Matthías Johannessen called Seyðisfjörður a 'pearl enclosed in a shell'. The community owes its origins to foreign merchants, mainly Danes, who started trading in the fjord in the mid-19th century. But the crucial factor in the evolution of the village was the establishment of the Icelandic herring fishery by Norwegians in 1870-1900. The Norwegians built up a number of herring-fishing facilities, and in a matter of years the little community grew into a boom town. Today, about 800 people live in Seyðisfjörður. The local economy has long been based on the fisheries, while light industry also flourishes. Tourism is playing a growing role, as the picturesque town in its spectacular surroundings attracts more and more visitors. The car/passenger ferry Norrøna, which plies between continental Europe and Iceland every summer, docks at Seyðisfjörður every Thursday. Seyðisfjörður has been a cosmopolitan community from its foundation, and the ferry service has contributed to ensuring that it remains so.
