[4] The entrance to the station was originally intended to be in the park Kungsträdgården, but due to the Elm Conflict in 1971 these plans had to change.

The cave-dwelling spider has lived on the station's walls ever since it opened for service in the mid-1970s, but scientists do not know exactly how it got there.

There is also moss growing on the walls that was previously thought to be extinct in the Stockholm region.

[5] In 2016 a team of scientists conducting a survey of the metro's wildlife discovered two previously unknown species of fungi covering the station walls.

Upon closer analysis the fungi turned out to be from a previously unknown genus, with unique DNA compositions.
