The aim of the article is to present the problem of revitalization of marketplaces in the context of the challenges they face in contemporary socio-economic conditions. This issue was developed based on desk research and inquiry conducted on a representative marketplace in Gdańsk Oliwa. They served to formulate guidelines for the implementation project aimed at improving the image and economic condition of traditional marketplaces in Poland. Despite significant importance for the local economy, traditional marketplaces are not able to compete with shopping malls and shopping centers, as a result of which they become unsustainable. The ongoing degradation of marketplace areas reduce their attractiveness and role they play in public spaces network. The authors of the project recognize that the solution to the issue of marginalization of traditional marketplaces is to strengthen their image in both physical and media realms. One of the proposed solutions is institutional support for marketplaces by non-governmental organizations involved in the revitalization and aestheticisation of urban areas.
