Creation of Nyholm The existence of Holmen originates in a wish to relocate the Danish Fleet from its earlier home at
Bremerholm. Since the city was growing rapidly, it was no longer practical to have the fleet stationed in the centre of the city. Being built out of timber, the vessels constituted a major hazard. Furthermore, the sailors disposed of their garbage by throwing it directly into the harbour, which had developed into a sanitary hazard as well. In 1680, a plan was conceived to move the fleet out of the city. Responsibility for the plan was given to Admiral
Niels Juel. From 1682–92
Christianshavns Vold was extended northwards to protect the area which had been chosen for the fleet. The extension had seven bastions, named for members of the Royal Family. In Carls and Wilhems Bastion, black powder depots were constructed. Built in 1688 and 1690, they are the oldest structures at Holmen. The northernmost bastion was Charlotte Amalies Bastion, and north of this two cannon batteries were established, "Batteriet Quintus" and "Batteriet Neptunus". The latter's name came from the sunken ship which was the foundation for the battery. This battery was later renamed to "Christiani Sixti Batteri", or "Christian VI's Battery". Today it is known as "Batteriet Sixtus" or just "Sixtus". The sinking of ships continued, loaded with mud from the harbour and trash from Copenhagen's streets. In certain streets, there could be more than one metre of trash, so there was plenty to take. This efforts gradually formed an island, which was given the name Nyholm. It was to this island that the naval shipyard was relocated. The first ship which was set to sea from this shipyard was the first
Dannebrog in 1692. Afterwards, the construction of all large ships was moved to Nyholm, and at Bremerholm, now called
Gammelholm, only smaller vessels were built. After 1692, several ships were built on Nyholm and in 1750, for the first time a Danish king,
Frederik V, was wearing a naval uniform in connection with the naming of a new ship. In 1807, following the
Second Battle of Copenhagen, the English destroyed three ships at the shipyard, but ship construction continued at Nyholm until 1918, after which ship construction and several other operations were moved to Frederiksholm, which was to the south. The shipyard was separated from the Navy and became a civilian operation with its own director.
Creation of Arsenaløen While development on Nyholm continued, a little island called Motzmanns Plads, just north of Christianshavn, was bought. Later it was renamed
Christiansholm. A new island was created by new reclamations, just east of Christiansholm. Here a large
arsenal was completed in 1770, giving rise to the island's name. Later the island was extended eastwards until reaching its current size in the middle of the 19th century. In 1860 Arsenaløen formed a land connection to Christianshavn, which became the main entrance to Holmen, known as Værftsbrovagten (English: The Yard Bridge Hard). Until then access to Holmen had been by ferry to Christiansholm, from where a bridge connected to Arsenaløen where to Holmen was entered through the
King's Gate.
Creation of Frederiksholm Around 1750, further reclamations created two small islands south of Nyholm, Balastøen (English: The Ballast Island) and Ankerøen (English: The Anchor Island), along with a larger island, Langøen (English: The Long Island). Bridges were built from Nyholm to Ballastøen, from Ballastøen to Ankerøen and from Ankerøen to Langøen. From Langøen's southern tip, a bridge was built to Arsenaløen. This happened towards the end of the 18th century. At this point, all of Holmen's islands were connected. East from Langøen, an atoll was found called "Mudderøen (English: The Mud Island). This area was reclaimed and annexed to Langeø, which at this stage was renamed Frederiksholm. In 1789 Frederiksholm had reached its current size. The original intention was to use the new area for
barracks for Navy personnel, but this plan was abandoned. Instead, a number of other buildings were built on the island, including storages for ship masts. After the
Gunboat War, a row of
boathouses were made for the storage of
gunboats. When Gammelholm was finally decommissioned by the Navy in 1869, most activities were moved to Frederiksholm, and in 1918 the shipyard at Nyholm was moved to Frederiksholm and the adjoining Dokøen.
Creation of Dokøen Land reclamations west of Langeø (Frederiksholm) and north of Christiansholm led to the establishment of two new islands for the storage of anchors and ships ballast after the first Anchor and Ballast Islands had become part of Nyholm. By further reclamations, they grew together and in 1858 a large
drydock was constructed at the island as a replacement for
Gammel Dok at Christianshavn. After this, the island became known as Dokøen (English: The Dock Island). In 1925 the island was annexed to Frederiksholm but kept its own name.
Closure of the naval base and redevelopment From 1690 to 1993 Holmen was the main base of the
Royal Danish Navy. After
World War II, two new bases were established in
Korsør and
Frederikshavn but even though more and more activities were relocated there, Holmen retained its status. In 1981 the naval shipyard closed. On 1 May 1993, the Holmen Naval Base was closed. == Historic buildings ==
