Below the ground of Stockholm, the capital of Sweden and the largest city in Scandinavia, lies the world\u2019s largest art exhibition. With 90 unique stations, the Stockholm subway represents a landmark of art in public spaces. Stockholm subway\u2019s first line open in 1950 and today, the extensive network of underground tunnels carries more than 1 million passengers every day to home or work or somewhere in between. And through the work of 150 artists, these daily journeys become all the more meaningful and acculturate for anyone roaming the Stockholm subway. Here are 6 stations to prove that Stockholm's subway system might be the world's largest public art gallery T-Centralen Station T-Centralen acts as the main hub of Stockholm\u2019s subway. The blue station represents quite appropriately the main hub of the blue line, opened up for traffic in 1975 becoming the first station to feature artwork and begining the city\u2019s underground art network. Kungstr\u00e4dg\u00e5rden Station Located in downtown Stockholm, Kungstr\u00e4dg\u00e5rden, roughly translated to \u201cKing\u2019s Garden\u201d lies under a royal historical area rich in history and not only. The station is a case study for historians or artists, but also of interest for biologists as the underground tunnel developed its own and unique fauna and flora with very particular animal and fungi species. R\u00e5dhuset Station Located under the Stockholm Court House from where the station got its name, the R\u00e5dhuset subway platform creates a surreal contrast between the raw and organic cave aesthetics with a strong, structural and imponent architecture feature as the column. Tekniska H\u00f6gskolan Station The station below the KTH Royal Institute of Technology opened in 1973 with artwork by award-winning artist Lennart M\u00f6rk. The station is a celebration to some of history\u2019s greatest thinkers such as Plato, DaVinci, Newton and their contributions to science and the fascinating history of the pursuit of knowledge. Solna Centrum Station Nicknamed \u201cthe gates of hell\u201d, Solna centrum is one of Stockholm subway\u2019s most visual striking stations due to the intense orange-red ceiling and meticulous details like trees and little houses, spread across the station walls. Tensta Station Tensta is a suburb of Stockholm where many people moving into the city found residence in the 70\u2019s. The station exhibits messages of welcoming, acceptance, equality, and love looking like a pre-history man cave full of rupestrian art.
