The study of linguistic landscape includes research into the usage of written language on certain public grounds. We can learn a lot from an area surrounding us, as well as from the sings written in those areas. Therefore, the aim of this work is to research the public signs written in the center of Split, the language on those signs, with the highlight on the grammatical, spelling, and lexical errors on them. The research was conducted from December 2023 until May 2024. The center of the city was chosen because it is the part most filled with written signs. This area is where both the local residents and tourists often reside, which certainly provides a diversity of signs and language. The results of the research show that most of the signs are written in Croatian. Apart from Croatian, another dominant language is English, which is present because of the large influence of tourism, taking into consideration that Split is a tourist destination. The research also showed insufficient knowledge of the norms of the Croatian standard language and the lack of usage of dialect in public signs. Signs written in dialect contribute towards language preservation. Since this research was only conducted in one area of the city of Split, future research should be conducted on other parts of the city, so as to get a full picture of the language landscape of Split.
