Planning and construction In the middle of the 19th century, Copenhagen's growth and the increasing
industrialization made it clear that the city's harbour was becoming too small and in the same time old plans to create a
free port were revitalized. In a plan from 1862 it was decided to dig out the area to allow access for the largest ocean-going vessels and use the materials removed for land fills along the coast. A suggestion to make all of
Amager into a duty-free zone was abolished and instead it was decided to create a free port in the area in the Svanemølle Bay north of the fortress
Kastellet. Construction began in 1891, prompted by
Germany's construction of the
Kiel Canal that was begun in 1887 and threatened Copenhagen's position.
Management and use The new free port was inaugurated on
9 November 1894. A private limited company,
Københavns Frihavns-Aktieselskab (KFA), was given a concession on operating the port by the Ministry of Interior Affairs. All shares in the Free Port Company was taken over by Port Authority in 1951 and the company was dissolved and replaced by
Københavns Frihavns- og Stevedoreselskab A/S in 1879.
Expansions In 1915–15, the free port was expanded with a new basin, Jronløn Basin (Danish: Kronløbsbasinet), located to the north. It blocked the access to the Kalkbrænderihavnen dock, making it necessary to dig out a new access canal to it. The next expansion of the free port took place between 1919 and 1931, creating the harbour basin now known as Orient Basin.
Late history The free port left its original grounds in 1985. An architectural competition was launched for the future use of the area. Among the entries were a proposal from
Jørn Utzon which included a highrise and several other buildings on Langelinie Pier but none of the submissions were realized. The Amerika Plads area was redeveloped in the 2000s. The free port is now located in
Nordhavnen and is part of
Copenhagen Malmö Port. ==Layout and key figures==
