Historical illustrations give us hypothetical visual reconstructions of the past, which contribute to their interpretation, knowledge, and understanding. The progress of software for the design and production of images has optimized the possibilities of generating models of educational and understandable illustrations of spaces, facts, and concepts of the past. At the same time, promoting historical recreation activities allows us to obtain photographic and moving images of a historical nature, which can be integrated into image processing software. This paper describes the experience of the DIDPATRI group (Heritage Education, comprehensive museography and new technologies) the University of Barcelona with the Battle of the Ebro (Spanish Civil War, 1938), concerning the design of models/educational illustrations of the conflict. The developed actions show that, with well-defined criteria, support for recreation, and basic but highly educational software that is understandable and replicable, iconographic models can be obtained at a reasonable cost. The final result provides us with the possibility to understand the past in greater detail. The heritage of the conflict gives us the possibility to reflect, thereby directly affecting the formation of quality citizenship.
