Stockholm’s Tunnelbana is not the world’s biggest metro system, and it does not need to be. What the Swedish capital lacks in mileage it makes up for below ground, where entire station halls were blasted out of bedrock, left gloriously raw, and handed over to artists. Ride a few stops in any direction and the daily commute starts to feel like wandering a cave system that someone has lovingly painted from floor to ceiling.
The travel photographers at Hand Luggage Only shot the images here, and their walkthrough, which we first found via Apartment Therapy, still holds up. We remain impressed by how vast these spaces are, and how the bold paint and murals reveal a more expressive side to Sweden than perhaps we are used to.
The World’s Longest Art Gallery
Stockholmers like to call the Tunnelbana the world’s longest art gallery, and the numbers back up the boast. The network stretches roughly 110 kilometers, and more than 90 of its 100 stations hold permanent works by over 150 artists. The tradition goes back to 1957, when Sweden decided that public art belonged in public transit and began commissioning artists alongside engineers. When the Blue Line was dug in the 1970s, planners made a radical choice and skipped the tile entirely. They sprayed the blasted bedrock with concrete, kept its cave-like contours, and let artists treat whole stations as canvases.
Nearly seventy years on, it remains one of the most generous public art programs on the planet, a civic gesture that turns everyday infrastructure into architecture worth crossing an ocean for.
Stations Worth Riding For
Start at T-Centralen, the hub where every line meets. In 1975, Per Olof Ultvedt covered the Blue Line platform in cool blue vines and flowers, along with silhouettes of the workers who built the station, and the effect is strangely calming in the busiest spot in the system. One stop away, Kungsträdgården plays out like an archaeological dig, with Ulrik Samuelson’s green ceilings, checkerboard floors, and salvaged fragments of old Stockholm buildings scattered through the hall.
Solna Centrum might be the most photographed of them all. Its ceiling glows a molten red above a kilometer-long spruce forest mural, painted in 1975 by Anders Åberg and Karl-Olov Björk as a quiet commentary on rural depopulation and the environment. Stadion answers with pure joy, a rainbow arcing across a sky-blue grotto in honor of the 1912 Olympic Games held next door.
Then there are the sleepers. Rådhuset sits under warm rust-colored rock that feels borrowed from a desert canyon, and out in Tensta, painted penguins and words of welcome fill a bright white cave that speaks directly to the neighborhood above. Every one of these detours costs nothing more than the ride itself.
The photographs only hint at the scale. These halls swallow sound, the painted ceilings hang low and heavy like weather, and the colors shift as trains push warm air through the tunnels.
Seeing It for the Price of a Ticket
The gallery is open whenever the trains are running, and admission is a standard SL fare. In summer, Stockholm’s transit authority offers free guided art walks with nothing required but a valid ticket. Going on your own is just as easy. Grab a day pass, start at T-Centralen, and ride the Blue Line outward, hopping off wherever a platform looks promising. The map below marks eight favorites.
We keep a running list of the most beautiful places on Earth, and Stockholm’s underground makes a strong case that some of them sit thirty meters below the street. For more journeys like this one, wander through our travel section.
