1. Hammerfest (a city in Finnmark, Norway; the northernmost city in the world; official name: Hammerfest)
   • 1895, Dr. Hans Reusch, Marius Hægstad, transl., Ei liti landkunna elder geografi [A little geography], page 62:

     Landet vert svært snaudt og audslegt, naar ein er komen um Trumsøy og endaa meir, naar du hev siglt framum Hamarfest, som er den nørdste byen i verdi.

     The land becomes very naked and barren, once you get past Tromsøya and even more when you’ve sailed ahead of Hammerfest, which is the northernmost city in the world.
