Spatial issues in Polish Cittaslow towns in the perspective of changes in the spatial planning system

The aim of the article is to analyze spatial issues in 36 towns belonging to the Polish network of Cittaslow, the most dynamically developing network of all 33 countries in the world and second in terms of size, after the founding Italian network. The main spatial analyses were preceded by an analysis of the literature on the Cittaslow network, especially in the context of research on Polish towns. The analyses concerned (1) certification criteria in the context of the spatial directions of the town’s development; (2) spatial structure of member towns and (3) local spatial development plans in force, which, as a rule, are the main spatial planning documents in Poland.
