The Stockholm subway system is said to be the world's longest art exhibit - 110 kilometres long. Travelling by subway is like travelling through an exciting story that extends from the artistic pioneers of the 1950s to the art experiments of today. Over 90 of the 100 subway stations in Stockholm have been decorated with sculptures, mosaics, paintings, installations, engravings, and reliefs by over 150 artists. 

The Kungsträdgården subway station looks like an archaeological excavation, with the remains of the old Stockholm Makalös palace. At Östermalmstorg the artist Siri Derkert highlights women's rights and peace and environmental issues.

This is a picture of me at Mörby Centrum on the red line, decorated by artists Gösta Wessel and Karin Ek. I found this station particularly interesting as you can only see how beautiful the colours are from a certain angle. I actually passed this wall many times and never noticed how truly beautiful it can be. If you have an SL card, you can make a full day of visiting each station at a minimal price, I would really recommend it.
