Commercial functions are very important to the process of urban revitalization. Various commercial forms of trade, such as markets, marketplaces, cloth halls have enriched the public spaces of cities over the centuries. Over the last 25 years of the free market in Poland, we have observed deformations within the urban structure caused by new types of commercial functions. The attractive functions of urban malls and shopping centers, which are usually placed inside, cause the degradation he streets located outside. Shopping centers, spread within the city and isolated by parking areas from pedestrian networks, contribute to the growth of inner peripheries.

Ventures within the historical city centers require the development of new instruments which would allow us to protect existing values.
