The study focuses on the spatial concentration of street art in Belfast within the context of the conflict in Northern Ireland and the influence of the city’s ethno-national composition on its distribution. Both majority- and minority-British areas featured loyalist (pro-British) murals. Nationalist (pro-Irish) art was present in areas with an Irish majority. There was a difference in the frequency of the themes depicted between districts, influenced by factors such as tragic events from the Troubles and the control of territory by paramilitary groups. In the city centre, street art unrelated to the subject of the study was observed. This can be attributed to restrictions on access to the area and limitations on organising public demonstrations in this part of Belfast during the Troubles, as well as to subsequent urban regeneration, the high proportion of foreign residents, and the presence of a large young population.
