Karlaplan was opened on 2 September 1967. It is named for a traffic circle with a striking fountain in the middle that lies at one end of the station (and where one of the station exits is located).

This lettering is used for the station signs on the platform at Karlaplan. Similar lettering was originally used for the signs at Östermalmstorg, and traces of that lettering are still visible.

On the northbound track wall at Karlaplan is this extensive work of photographic art by Larseric Vänerlöf called "Den dagen den sorgen," or in English, "Don't borrow trouble," depicting events in Sweden during the 1900s. This photo only shows part of the work; it's almost as long as the platform.

An oblique view of the passage at the center point of the platform. The sign, which I'm sorry to say didn't come out here, is for a little hardware/key/shoe service store that, as far as I know, is the only commercial enterprise still operating on any subway platform in Stockholm.
