landfill, just east of Christianholm, where a large arsenal was built and finished in 1770. Later, this island was named Arsenaløen and was expanded to the east. Originally, a main gate existed to Nyholm. Nyholm wasn't just a name for the northernmost island but was the name for the area used by the navy. Access to the area required sailing to Holmen. A ferry sailed to Christiansholm, where one went over a bridge to Arsenaløen. Here, one could go to Nyholm though a gate, which faced the canal between Arsenaløen and Christiansholm. The gate was called "The Kings Gate". It is not visited by many people anymore. This is because in the middle of the 19th century, Arsenaløen formed a land connection with Christianshavn, so a new main entrance was created to Holmen, the so-called Warf Bridge Guard, or Værftsbrovagt. The ferry to Christiansholm stopped and the Kings Gate was no longer used. Frederiksholm Around 1750, dumping of dirt and fill created two small islands south of Nyholm, "Ballastøen" and "Ankerøen", along with a larger island, "Langøen". From Nyholm, a bridge was built to Ballastøen and from Ballastøen to Ankerøen and from Ankerøen to Langøen. From Langøen's southern end, a bridge was built to Arsenaløen. This happened in the later part of the 18th century. At this point, all of Holmen's islands were connected. East from Langøen, an atoll was found called "Mudderøen"; the area between Mudderøen (including Mudderøen itself) and Langøen was filled, and "Frederiksholm" was created. This area was supposed to become a residential area for Navy personnel, but this plan was never followed through. Instead, the area became a storage area for ship masts, along with a row of other buildings on the island. After the Gunboat War, slips were made for the storage of cannon ships. When Nyholm, as mentioned, was expanded together with Ballastøen and Ankerøen to present day Nyholm, Ankerøen and Ballastøen were replaced with Ballasø and Ankerø, which were created west of Frederiksholm.
