Public spaces in the historic cores of cities need to adapt to changing requirements for their use, reflecting the current needs of their users. High-quality public spaces provide a safe, accessible, suitable and pleasant environment for various types of activities and meet the needs of residents - users. Based on their good functioning, cities are generally evaluated by their inhabitants as more or less attractive for life. Within the project “LIVA - The concept of livability in the context of small towns” we have examined public spaces in the historic city cores of selected small cities in Slovakia, to identify the problems and potentials of forming environmentally and people-friendly public spaces. The research shows, that today’s architectural-urban forms of public spaces in the historical centers of small towns in Slovakia are burdened with many problems, the most serious of which are usually their unsatisfactory functional content, unsatisfactory organization of transit transport, the poor state of public greenery, or unsatisfactory conditions of the physical environment – pavements or equipment with urban furnishings. The public spaces reflect the overall problems of small towns, remoteness, lack of investments, departure of young people and aging of the population, resulting in a lack of basic infrastructure and underdeveloped amenities for providing public services. In many cases, the historical centers of small towns do not provide sufficient attractiveness for businesses and cultural and social facilities in the parterre of buildings, nor variability of functional use of the public space. On the other hand, public spaces in the centers of small cities show the potential to offer a better quality of the environment. The central zones, the amenities, and public services, green infrastructure or recreation and sports areas in small cities are usually accessible within walking distances, which supports pedestrian movement and reduces the use of cars. The historical cores of small towns in many cases successfully preserved their cultural heritage values, their historical identity, and their character.
