Great free museum. Located in central Mitte but for some reason not well known. A permanent exhibition of Stasi (DDR secret service) survelliance devices and information about daily life in the DDR.
The government runs it which is why it is free. There are sometimes old East Germans there filling in government forms to access their old Stasi files. Very interesting museum and the people are very friendly. The museum book costs only 2.50 Euro in English also.
Right below Pariserplatz. I think off Wilhelmstrasse Strasse in Mitte. U6 Stadtmitte
