Background: The ageing population presents new challenges for modern cities, particularly in adapting public spaces to meet the needs of senior citizens. This study aims to identify and analyse the inclusivity of public spaces in selected districts of Gdańsk, considering urban and social factors, and assess how well these spaces accommodate the needs of the elderly population. Material and Methods: The study began with a demographic analysis of Gdańsk 2003–2023, focusing on the increasing number of residents aged ≥60 years. Based on this analysis, 3 districts were selected: Przymorze Wielkie, Młyniska, and Wzgórze Mickiewicza. They differ in terms of building typology and access to public transport and green spaces, which were studied using quality research methods. Finally, a geo-survey was conducted to collect spatial data on how seniors interact with their environment and identify barriers to accessibility in public spaces. Results: The demographic analysis revealed a rapid increase in the elderly population, which accounted for 28.1% of Gdańsk’s population in 2022. The study found varying levels of access to green spaces and the quality of infrastructure in the selected districts. In Przymorze Wielkie, most seniors were satisfied with the availability of green spaces, while in Młyniska and Wzgórze Mickiewicza satisfaction levels were significantly lower. Additionally, the study highlighted differences in access to public transportation and infrastructure designed to meet the needs of older adults. Conclusions: The findings indicate a need to adapt public spaces and urban infrastructure to the needs of the ageing population. The diverse experiences of seniors across the districts of Gdańsk underscore the necessity for targeted urban interventions to improve the quality of life for older adults, particularly by enhancing access to green spaces, infrastructure, and essential services.
