1. Die Steinmühle
Die Steinmühle wurde 1303 als Getreidemühle von den Zisterziensermönchen aus dem Kloster Zinn erbaut und von diesen betrieben. Bis 1766 wurde die Mühle als Getreidemühle genutzt, bis der damalige Mühlenmeister eine Genehmigung zur Anlegung einer Schneidemühle (Sägewerk) erhielt.
1845 wurde sie wieder abgerissen und danach als Ölmühle wiederaufgebaut. Ende 19. Jahrhunderts wurde auf Dampfkraft erweitert und die Mühle zur Strohpapierstoff-Fabrik umgebaut. Sie wurde auch weiter als Dampfmühle genutzt. 1918 firmiert die Mühle als „G. Thiele Steinmühle“. Inhaber war Emil Gericke, der Schwiegersohn von G.Thiele. 1934 wurde die Dampfmaschine durch einen Motor ersetzt und die Mühle vergrößert.
The district party school of the SED
The shell of the building was built between 1938 and 1942. It was planned as a school building, but due to the Second World War, the building project was not initially completed. It was not until 1951 to 1955 that the building was expanded to become an SED party school. In the 1970s there was a significant expansion with many lecture rooms and a 10-storey accommodation building. In the 1990s it was used by the city and sold in 2002. The huge area has been empty since then. The inside makes a badly rotten impression. Everything that was useful was disposed of. Windows are smashed or secured with wooden panels. The old SED discotheque in the basement of the old building was interesting for the budding party cadres.
The district party school (BPS) of the Socialist Unity Party of Germany (SED) had the task of ideologically training young SED workers to become potential leaders in the GDR party and state apparatus. After the “Karl Marx” college in Berlin, it was the state party's second highest cadre school. There were 15 district party schools across the GDR. The SED district party school offered political and technical training for management functions. Without a visit to such an institution, it was impossible to take a leadership position in the state or party. The district party schools were thus an important recruiting reservoir for senior cadres. They provided the personnel for building up the party and state apparatus; their graduates were automatically nomenklatura cadres of the SED. The courses lasted up to a year.
