Monuments and memorials are often shaped as a wall, the fundamental importance of this temporary art monument lies in the participation of the visitors. The refugees problem in Europe is a very actual and dramatic portfolio for the United Nations and individual states worldwide. Dramatic consequences of (civil) wars, repression and political corruption forces people to leave their home countries. With the emigration to safe places they start a new life. The concept of the project is that this wall is like a physical barrier dividing spaces and representing an obsacle to be passed in order to achieve a certain goal. Petchkovsky is covering the barrier with empty dossiers as a methaphor for the fact that the UN dossiers on refugees is an empty one, not able to solve the problem on a concrete and durable base.
