The subway has been regarded as the world's longest art gallery due to countless artworks presented throughout its 90 stations. Adorned with mosaics, engravings, reliefs, sculptures and paintings, those stations would surely amaze anyone who would take a gander at them.
Some of the best stations you should definitely pay some extra visits include Kungsträdgården, Rådhuset, and Tensta (from the Blue Line); Bagarmossen, Hötorget, and Thorildsplan (from the Green Line); and Tekniska Högskolan, and Stadion (from the Red Line).
Of 100 metro stations that the Stockholm subway has been operating for over two decades now, 53 are above ground, while the 47 left are run underground. On average, the daily ridership of the metro is 898,630 passengers, thus accumulating them 328 million passengers every year.
In 2013, the management of the subway announced that they would be working on many extensions from 2016, two of which are the Blue Line extensions. These projects would mean hassle-free ways to get access to decorative sections of the metro.
The plan to construct the metro was first conceptualized in 1941. Even so, the earliest line of the Stockholm subway was opened for public use in October 1950.
