Hammerfest , a seaport of Norway, in the bailiwick of Finmark, on the island of Kvaio, in lat. 70° 40' N., Ion. 23° 42' E., 57 m. S. W. of the North cape; pop. about 1,000. It is celebrated as the most northern town in the world, and for its lively trade with Russia, England, and other countries. The cod fishery in the Hammerfest district in 1871 yielded about 5,000,000 fish, or nearly one half of the cod caught in Finmark. Over 200 fishing boats and 100 large vessels frequent the bay annually. Cod-liver oil is largely prepared, and various skins, walrus teeth, and other articles are exported. A number of small sloops are engaged in the trade with Spitzbergen, where reindeer, walrus, and white bears are killed. Although the port is in so high a latitude, navigation is seldom interrupted. The harbor is defended by a fort. A granite pillar in the rear of the English vice-consulate marks the commencement of the great European arc measured by Russia, Sweden, and Norway, 1816-'52.
