Sports facilities are built objects and outdoor surfaces in the built environment, with significant impacts and effects on society, economy and environment. High-quality sports facilities, their proper spatial distribution and accessibility are important factors in the development of sport and sports-related activities and influence the quality of life. Data on sports facilities and their spatial distribution are a measure for the quality of sports areas. They represent the basis for strategies for the development of sports facilities on local and national levels, their placement in the built environment, and support the development of other sports-related activities. This article highlights the definition of a sports facility and its importance to the built environment and society. The survey includes an analysis of spatial and other databases on sports facilities in Slovenia and an assessment of their quality.
