Linguistic Landscape as Cultural Heritage: Reflection of the Multilingual History and Spatial Identity of Istria, Croatia—Late 19th–21st Century

The linguistic landscape is a significant aspect of the cultural landscape and heritage. Istria, a region and peninsula located in the Republic of Croatia, has experienced various influences over the years that have shaped language use, impacting the linguistic landscape and the identity of the local population. This paper aims to investigate how the linguistic and spatial identity of the people in Istria has been represented in the region’s cultural landscape during two comparative periods: the turn of the 20th century (the local population’s fight for their national language against the languages imposed by the European powers that governed this region—Italy and Austria) and the turn of the 21st century (the status of minorities in the present Croatian region of Istria). This diachronic research employs a cross-sectional method to compare findings and establish cause-and-effect relationships. This study involves analyzing linguistic data from historical postcards, conducting field studies, and using the pin placement feature on Google Maps to assess recent periods. This research identified Italian and Croatian as the dominant languages during different periods, with English being increasingly prevalent in contemporary times. The results demonstrated that the spatial identity of the Italian minority community is strongly reflected in the linguistic landscape, primarily due to bilateral interstate agreements.
