During the following years Kielnhofer put his time guardians in public places like in front of ancient castles, squares, old mines or in parks. They travelled to several countries and were part of many exhibitions. In his works of art Manfred Kielnhofer deals with the natural human desire for security. Thus his oeuvre reflects genuine exploration, consideration and discussion of current as well as historic moods and sensibilities of his social environment.
