The Stockholm subway system is said to be the world’s longest art exhibit – 110 kilometers long. Traveling by subway is like traveling through an exciting story that extends from the artistic pioneers of the 1950’s 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 Kungstradgarden subway station looks like an archaeological excavation, with the remains of the old Stockholm Makalos Palace. At Ostermalmstorg the artist Siri Derkert highlights women’s rights and peace and environmental issues.
