HHole for Mannheim (2006-∞) was a permanent multimedia installation in the "Athene-Trakt" of the Kunsthalle Mannheim created by NatHalie Braun Barends. The Kunsthalle is As of 2015 under reconstruction; the installation was removed. Following a legal dispute and a decision of a German Federal Court which stated that the removal of the work does not infringe the artist's intellectual property rights, the installation will most likely not be rebuilt afterwards.
