Tøjhuset was built from 1593-1604 as an arsenal, part of a new naval harbour constructed by Christian IV.
It is 163 metres long and built around a central harbour basin.
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.
In 1926 the current museum was founded in the building.

Outside the Tøjhus building, facing the harbour, stood the Isted Lion which was reclaimed from Germany in 1945 after World War II.
It was moved to Flensburg in 2011.
