In this paper were investigated the attitudes of the respondents towards the commercialization of the public space of the city of Split. Focusing on three significant public spaces; Marjan, Riva and public beaches. With regard to these three spaces, we determined the respondents' attitudes about the suitability of commercial content in these public spaces, the amount of space they occupy and were interested in their opinions on how to increase the attractiveness of these public spaces to citizens. The survey was conducted in August 2020, using an online survey method, on a sample of 150 respondents, adult citizens of Split. Bearing in mind that this is a convenient sample, numerically uneven with respect to the gender of the respondents, we can draw the following conclusions. The results of data processing indicate a negative attitude of respondents towards the commercialization of public space. This negative attitude is mostly expressed by the desire to reduce the amount of space that commercial content occupies, which confirmed the second hypothesis. These attitudes differ with regard to the public space in question. The biggest opposition is to the commercialization of Marjan. Attitudes also differ with respect to the gender of the respondents, the results show that men have more negative attitudes towards commercialization compared to women, thus confirming the first hypothesis. The results also show that the residential area of the respondents does not significantly affect their attitudes towards the commercialization of any of these three public spaces, therefore the third hypothesis was rejected. In conclusion, we can say that despite the variations with regard to gender, the majority of respondents have negative attitudes towards the commercialization of public space and most believe that reducing the amount of commercial contents would increase the attractiveness of these three public spaces to the citizens of Split.
