Horten is a town and municipality on the western shore of the Oslofjord in southern Norway. Historically shaped by its role as a naval base, the community combines maritime industry, museums and coastal recreation. Population figures have varied over time; in 2007 the town counted about 25,000 residents.

Geography and administration

Horten sits within the county of Vestfold og Telemark after recent regional reforms. The town occupies a coastal landscape of harbour areas, residential neighbourhoods and recreational shoreline. Its position on the Oslofjord places it within easy reach of other population centres in the Oslo region by road and regional transport.

History and naval heritage

The modern town developed around naval facilities established in the 19th century. Karljohansvern, the principal naval base and dockyard, dominated local life for generations and left a legacy of waterfront infrastructure and military buildings. Many of these sites now house cultural institutions and businesses, preserving Horten’s maritime identity.

Economy, culture and attractions

Maritime activities, light industry and public services are important to the local economy. Horten hosts museums and exhibitions that interpret naval and seafaring history, and its sheltered bays, marinas and promenades make the town popular for boating and seaside recreation.
