The original Viking Hotel was built in 1905 at 420 Broadway by Ole C. ("Chris") Lindvig and Christ A. Losness. In 1910 Charles H. Porritt (a Fargo contractor) built a new Viking hotel and restaurant across the street, at 413 Broadway. The Viking Hotel was a popular rallying point for those with Scandinavian heritage. Lindvig and Losness ran the hotel until 1940, when it was sold by First Federal Savings and Loan (which gained possession following Porritt’s death) to Gomer D. Anderson and K.S. ("Sparky") Davey of Fargo. The new owners remodeled the building and reopened it as the Bison Hotel.
