What constitutes human fascination for spaces under the ground? What makes underground movements and cultures trigger our imagination? Why does the underworld appear in so many different cultures? Throughout time and culture underground space has been a source of fascination. Through excavations and analyses, researchers endeavour to uncover its supposed secrets. Equally, the underworld of the human psyche is thought of as a space to ‘excavate’ in order to find hidden individual and collective emotions dwelling in the subconscious. Underground has also come to signify hidden and secret resistance and alternatives to oppressive systems – cultural, social or political. The underground contains negotiable contrasts. In the interdisciplinary Project Underground Museion investigates the internal ambiguities and tensions in the concept of underground-underworld. Researchers from various disciplines have dealt with the topic from their individual perspectives. The aim has also been to present some aspects of the underground concept in the form of an exhibition in the Museum of World Culture. The exhibition Take Action: 83 ways to change the world shows examples from the political underground. A number of the texts here are also available in Swedish in different versions in issue 4.07 of the journal Glänta, together with other investigations of the underground for those who really want to get down under.
