The presented research concerns a multi-faceted assessment of the existing condition of selected Polish health resorts. The aim of the research was to apply the above-mentioned evaluation in the context of possibilities to improve the condition of the space, attractiveness, and functioning of Polish spas that have been struggling with a number of problems of a political and economic nature, which originated in World War Two. Although intended to improve the functional environment of health resorts, the Health Resort Act contains provisions perceived as barriers to the development of health-related and other associated functions that are necessary for the appropriate operation of health resorts. This leads to a conclusion that the function – however deeply rooted in Polish culture – requires a new approach to health resort functioning in today’s circumstances. The new approach should be founded on a deep, careful, and detailed diagnosis of the condition of health resorts in Poland, which will perhaps enable the application of a multi-faceted assessment of the existing condition (MCSA). MCSA is modelled on a method developed in the 1970s in the United States of America by a landscape architect and spatial planner Ian McHarg. The main idea behind the development and application of this assessment method is to facilitate decision-making for planning, design, and investment activities, with a particular focus on local government. The case study carried out by the authors concerns two Polish health resorts located in the Małopolskie Voivodeship.
