Finally, two modern day visitors, no doubt a bit shell-shocked at the extent of the surveillance and luxury in the heart of this former socialist republic, try to regain their bearings by leafing through the Minister's precious map collection.
I hope you got a slight feeling for the building from the above, and that you are not too disappointed at the absence of medieval interrogation and torture rooms. This was the administrative HQ of the Stasi and that is what the museum is about. There is a video playing in a downstairs conference room outlining the Stasi's history and showing the detention/interrogation rooms which are in a different location.
If you want to see the Stasi in action, including briefly in this building, and, at the same time watch a good film with an excellent plot, check out
The Lives of Others. Make sure you have the version with subtitles. The version of the DVD with the English title should automatically ensure that. If you want the technical details on the film check it out on
Wikipedia and, if you have any intention of watching the film itself, don't read the plot in advance.
