the museum gives you "first hand" insight in the terrible time of the red terror. It was opend in 2010, is free of charge(doantions are welcome) and there are several volunteers (survivors of the red terror) who can show you around and explain everything to you. It is terribly upsetting what they show/ tell you (for ex. How they were foltered ect) but it is part of the history and shall not be forgotten. if you prefer you can also wander through the museum on your own- the explanations are in Amharic and English. Very moving!
