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.
Former government hospital of the GDR
From 1949 to 1976 the government hospital of the GDR was located in Berlin-Mitte, in 1976 this "special clinic" was built hidden in a wooded area in Berlin-Buch. It had the name not because of the special medical possibilities, but because of the special patients - only the "very highest" management level was admitted: members of the government, the SED Central Committee and the Politburo, as well as diplomats. The "government hospital" was of course taboo for ordinary people from the GDR. Nobody came in without a special ID. A nuclear shelter and a swimming pool were even built for them. The equipment was state-of-the-art, and a lot of western technology was used. There was also no shortage of medication here, in contrast to the rest of the GDR. One of the two computed tomographs (CT) of the GDR was located in the government hospital from the mid-1980s. In 1980 the also top-secret "Stasi Clinic" was built in a forest next door. In the 1970s and 1980s, the clinics in Berlin-Buch were not only the largest hospital in the GDR, but also the largest hospital complex in Europe, with over 3,000 beds. At the beginning of 1990 the hospital opened for the first time to normal citizens, to the "working people from Berlin companies".
A few months later, the People's Chamber decided that the house and the Stasi clinic should be incorporated into the Buch municipal clinic. In 2001 the meanwhile deficit Buch Clinic together with the government hospital was sold by the Berlin Senate to the "Helios Kliniken", which undertook to build modern clinic buildings. These were finished in 2007. The hospital has been empty since then. There are currently plans to demolish the building and the neighboring Stasi clinic and build 3,000 apartments here. The current state of the building, which is characterized by severe vandalism, does not allow anything else.
