[2] Tøjhuset was built from 1593 to 1604 as an arsenal, part of a new naval harbour constructed by Christian IV.

The building served as an arsenal well into the 19th century but already from the 1680s, it also housed historic collections.

In the 1880s the building had become too small and a new arsenal was constructed in what is now known as the district Islands Brygge.

Outside the Tøjhus building, facing the harbour, stood the Isted Lion which was reclaimed from Germany in 1945 after World War II.

[4] More than 8000 swords, pistols, armours, machine guns and other weapons and military paraphernalia are displayed in the museum's Great Gallery and the Canon Galley boasts more than 300 canons dating from the 16th century to present days.
