Dotrščina Memorial Park is one of the largest parks in Zagreb and the site of the largest mass crime in the history of the city. During World War II, the area of Dotrščina was used as a site for the mass execution of antifascists, Serbs, Jews, and other victims of the Ustaše regime. The history of Dotrščina is relatively unknown among the citizens of Zagreb. The characteristic terrain and symbolic monuments in the park provide a symbolic basis for the creation of a visual identity that will address the issue of preserving the relatively unknown heritage of the park. In its current state, Dotrščina Memorial Park does not have a developed signage system. Developing a signage system has the potential to enable visitors to easily navigate the location and educate them about the history of the park, as well as the authors and symbolic significance of the monuments in Dotrščina. The visual identity is envisioned as a powerful and effective tool for presenting the place of memory and cultural heritage. The visual identity should demonstrate the interest and cultural value of this location while showing respect for the victims who lost their lives here. Defined graphic standards will express the seriousness of this topic and their application will contribute to the preservation of the cultural heritage of Dotrščina. The visual identity should avoid the interpretation of the location as exclusively a mass grave site and focus on the park's nature and its content. The creation of a visual identity for Dotrščina Memorial Park has the potential to educate visitors about the historical purpose of the park, the authors, and the symbolic value of the monuments that are located there. It can also generate interest among visitors towards the park's content and promote the cultural heritage of this location.
