peer reviewed ; In this article we outline how corpus-based studies can contribute to the methodology of linguistic landscape research. Linguistic-landscape research can be roughly understood as the “study of writing on display in the public sphere” (Coulmas 2009: 14). From a historical perspective, we investigate the emergence and use of the public sphere as a place of attention for official top-down communication in Luxembourg. Based on a large corpus of public announcements of the municipality of the city of Luxembourg, the history of public top-down communication is analysed by taking into account both sociolinguistic and linguistic factors. The analysis reveals that the public announcements are increasingly typographically and linguistically adapted to the conditions of public perception and self-reading in the course of time – whereby initially the multimodal embedding of the older presentation form is maintained.
