"No visit to Kigali (or Rwanda in general) is complete without a visit to the Kigali Genocide Memorial. Give yourself at least an hour to wind your way through the permanent collection, which integrates photography and video with personal accounts of the genocide from survivors. An outdoor garden and burial site acts as the final resting place for more than 250,000 victims of the devastating event that saw more than 800,000 Rwandans killed."
