Keeping records and documenting the anonymous building heritage in Kozjanski  Park is an international, Bavarian –Slovenian project, organised by Kozjanski Park  and the Bavarian Slovenian Society.

The Letter of Intent was signed on the 16th of February, 1999. It was signed both by  organizers and project partners that decided to take part; University of Maribor, University of Ljubljana – Faculty of Architecture and Technical High School from Regensburg. For the first three years, the project was equally funded by the Free State of Bavaria and the Slovenian Ministry of Culture. Today, the project is financed solely by the Ministry of Culture.

The protected area of Kozjanski Park is divided into squares of 1 sq. kilometre. The heritage inventory is based on these so called »plan squares«. The project started in 1999 and by 2003 84 sq. km had been processed (in 91 plan squares, since not all of them lie completely within the park). This covers approx. 45% of the total protected area. So far we have identified over 3000 built structures and 1161 of them have been documented in detail.

Field work is performed by the students from Ljubljana's Faculty of Architecture and Regensburg's Technical High School (Department of Architecture). The project was presented in Regensburg on two occasions, as well as several times in the Administration Centre of Kozjanski Park. Moreover, we have organised symposiums in 1997, 1999 and 2002 where we discussed rural building heritage and the possibilities for its preservation.
