Square depression is a project, which was originaly designed in 1977, when Burce Nauman was invited among nine other artists by Kaspar König to do a sculpture for an open space. It was built 30 years later in the campus of the university’s department of natural sciences Munster. Square depression is an inverted pyramid, ‘walk in’ sculpture made of white concrete. The aim was to create a space, where one could experience a feeling of being isolated, helpless and alone.
