Stockholm’s metro system was never meant to be a cultural landmark, yet it has become one of the city’s most unexpected artistic treasures. Dubbed the 'World’s Longest Art Gallery', the Tunnelbana has become an underground museum, where every station tells a different story through murals, sculptures, engravings, and installations.
According to The Guardian, since 1957, more than 150 artists have transformed over 90 stations into immersive public art spaces. What began as a functional subway system has evolved into a dynamic timeline of Swedish creativity, political discourse, and artistic experimentation, making a mundane commute feel like a gallery tour.

A Vision of Art for Everyone: The Origins of Metro Art in Stockholm
The idea of integrating art into Stockholm’s metro wasn't as much about aesthetics as it was about accessibility. In the post-war era, Sweden’s Social Democratic Party championed the Folkhemmet (“People’s Home”) ideology, which aimed to make culture and welfare available to all. Art was no longer to be confined to museums but embedded in everyday life. As The Guardian notes, this vision took shape in 1957 at T-Centralen, where Per Olof Ultvedt adorned the station with serene blue-and-white floral motifs, honoring the workers who built the metro. According to Thrillist, as Stockholm expanded, the art followed, evolving with the decades, turning the underground into a vibrant, ever-changing artistic landscape that reflects the city’s cultural heartbeat.
Östermalmstorg: A Tribute to Feminism and Activism
The stations themselves serve as snapshots of the era they were built in, mirroring the dominant artistic and political themes of their time. At Östermalmstorg, artist Siri Derkert carved messages of feminism, peace, and environmentalism into the station’s concrete walls in 1965. Happiest Outdoors notes that, featuring figures like Virginia Woolf and Hypatia, the engravings reflect Derkert’s commitment to activism. Designed at the height of the Cold War, the inscriptions feel both timeless and urgent, whispering reminders of past struggles while urging commuters to carry those ideals forward.
Solna Centrum: A Vivid Warning on Environmental Destruction
Solna Centrum is one of the most visually striking stations in the entire system. Its blood-red ceiling, looming over an endless green forest mural, creates an unsettling yet mesmerizing contrast that is impossible to ignore. Painted in 1975 by Anders Åberg and Karl-Olov Björk, the station tells a story of rural depopulation and environmental destruction, capturing the anxieties of a nation grappling with modernization, as The Guardian reports. The stark color palette makes it an unforgettable stop—an artistic warning disguised as public decor. Even decades later, its message resonates, reflecting contemporary concerns about climate change, deforestation, and urbanization. It proves that the most impactful art doesn’t need a frame—it just needs a space where people will see it every day..

Kungsträdgården: An Underground Time Capsule
Kungsträdgården is an underground archaeological wonder, a station built from the remnants of Stockholm’s past. Designed by Ulrik Samuelson, the space is filled with sculptures, broken columns, and relics from demolished buildings, arranged like artifacts from a lost civilization, as noted by Thrillist. The station’s boldred, white, and green color scheme, combined with eerie lighting, enhances the feeling of stepping into another era. Even the moss-covered stones and rare underground plant life add to the illusion of an abandoned world beneath the city. It is a station that speaks to the fragility of history, reminding passengers that progress often comes at the cost of what once stood before it.
Stadion: A Celebration of Color and Identity
At Stadion, the metro transforms into a celebration of light and color. With its massive rainbow mural, the station is one of Stockholm’s most recognizable and uplifting landmarks. Painted in 1973 by Åke Pallarp and Enno Hallek, the vibrant arch was originally designed to make the underground space feel less oppressive, but, according to Happiest Outdoors, over time, it has become a proud symbol of LGBTQ+ rights in Sweden. Located near the site of the 1912 Olympics, the station also honors the spirit of sportsmanship and international unity. Its atmosphere is warm, celebratory, and inclusive—a testament to the power of public art to create spaces where people feel seen, welcomed, and represented.
An Evolving Art Movement Below the City
What makes Stockholm’s metro art unique is its ability to evolve. Unlike traditional museums, where exhibits remain static, this underground gallery is a living, breathing entity that shifts with the times. The Guardian reports that the earliest designs, such as T-Centralen, were minimalist, integrating public spaces with art to create a sense of tranquility. By the 1970s, the focus shifted toward political messaging, with stations like Solna Centrum serving as bold statements on deforestation and industrialization.
By the 1980s and 1990s, art in the metro became more introspective, as seen in Fruängen, where mosaics depict different phases of life, turning the station into a meditation on time and memory. Today, contemporary artists are adding digital and interactive elements, ensuring that the Tunnelbana remains a relevant and ever-changing canvas for future generations.
Beyond Aesthetics: The Functional Role of Metro Art
Beyond its aesthetic appeal, Stockholm’s metro art serves a functional purpose. The distinct visual themes help passengers navigate the system more intuitively, allowing them to recognize stations at a glance—a crucial feature for tourists and children. "It’s a wayfinding system as much as an artistic experience," explains Emma Sahlman, press officer at Region Stockholm, as reported by Thrillist. In a city where the winters are long and dark, the vibrant murals and sculptures also provide a psychological boost, transforming the daily commute into something far more engaging.
