Gullmarsplan, Transit hub and pedestrian zone in Johanneshov, Sweden.

Gullmarsplan is an 80 by 50 metre square in Johanneshov, paved with cobblestones in fan patterns crossed by bands of lighter stone. A line of tall, slim pillars of pale yellow-tan stone on dark grey bases stands on its right side, with a black bench among them. The square was repaved during a 2001–2003 refurbishment led by landscape architect Lars Ström.

The plaza took shape during 1940s urban expansion when Stockholm planned new connections between districts, with the metro station opening in 1950 as the fourth station on the network. Additional transit lines were added over decades, gradually transforming the intersection into a major hub.

The name Gullmarsplan, fixed in 1944, comes from the Gullmarn fjord in Bohuslän. The square hosts the annual Stockholm Japan Expo, and the opera Kurfursten is set in its metro station. A post horn remains on the former post office's brick facade.

Pathways are clearly marked and easy to follow when transferring between transit systems, with good lighting and accessibility features throughout the interchange area. Arriving visitors can orient themselves quickly since the different transport lines converge in a compact space.

The moving light sign of Sparbanken's piggy bank, with coins dropping into it, was a well-liked feature of the square until it was removed in the late 1980s when the bank changed its name. The large post horn remains on the brick facade of the former post office Johanneshov 1, designed by Lars-Erik Lallerstedt.
