The Shrine of Struggle and Martyrdom is located in the left wing of the Ministry of Education, which housed the headquarters of the Police and Security Service during the occupation. The basement was used as an interrogation prison. Visitors can access and see the collective cells, known as "trams", corridors, isolation rooms and the office of the Gestapo Guard. The walls, window frames, and floors are covered with thousands of inscriptions and texts of prayers, meditations on death, initials, names, titles, prison calendars, clocks, crosses, and many drawings, which in turn become the legacy of those who suffered brutally in this place.
