FREDRIKSTAD (FREDERIKSTAD), a seaport and manufac turing town of Norway in Smaalenene amt (county), 58 m. S. by E. of Oslo by rail. Pop. (1930) 14,T or. It lies at the mouth and on the eastern shore of the Oslo fjord, occupying both banks of the river Glommen, which, descending from the richly-wooded district of Osterdal, floats down vast quantities of timber. The new town on the right bank is therefore a centre of the timber export trade. Brick making and granite quarrying are important as well as the timber trade. The harbour is kept open in winter by an ice breaker. In the vicinity is the island Hanko, a Norwegian seaside resort. The old town on the lef t bank was founded by Frederick II. in 1567. It was for a long time strongly fortified, and in 1716 Charles XII. of Sweden failed to capture it.
