The exhibition was realized, but at the same time, during the many meetings, the idea was developed to found Forum Konkrete Kunst . Rational, reductive and constructive artists were to present their work which would remain their property. The Romanesque Peterskirche was a challenging location. The spirituality, which can be found in pure geometry, unites the Romanesque structure of the building and the analitic approach which is the foundation of concrete art. A wooden structure was added by Napoleon who used the building to house his troups.
Floors supported by wooden posts divide the interior into sub-spaces.
The colection of concrete art is presented on the ground floor between alternating stone and wooden columns. On the upper floor the cultural department of Erfurt organizes exhibitions which complement the more permanent collection. The last exhibition in the year 2000 is Vier Nationen Vier R ume .
