The town's centre lies on flat land between these two rivers. In addition, the town is surrounded by mountains, green hills, and forests. The Øyfjellet mountain (814 metres) just west of the town is a well-known landmark..As a rapidly growing town, Mosjøen was in 1875 granted staple rights and in 1876 separated from Vefsn as a town municipality. It is the oldest town in theHelgeland region, and only Bodø is older within the county. It was again merged with Vefsn on 1 January 1962. Since 1998, the town has modern town status..Mosjøen's business life contains both traditional and modern companies as well as a wide spectre of branches, including trade, handcraft, finance, transportation, and tourism. The town is a commercial centre in the region, attracting customers from smaller neighbouring towns and rural municipalities..Beside Mo i Rana and Narvik, Mosjøen is one of the industrial towns in Nordland. Most important is the Mosjøen Aluminum Plant, owned by Alcoa. The town's second period of industry began shortly after the Second World War. The first period began as early as in 1866, when Englishmen established sawmills there.
