Abstract: The post-communist policies on urban restructuring were the driving force in redundant and marginalized spaces’ reproduction in all Romanian cities and towns. The paper investigates post-communist urban ecologies and derelict urban environments in Romanian small-sized municipalities, since these issues remain peripheral in the contemporary research on post-communist urban identity formation of the cities. The research was conducted in the town of Lugoj of Romania, from 2012 to 2016. It bases on empirical data provided by ethnographic analysis, quantitative approach and qualitative investigation. The results unveil a massive decline of some urban areas managed by post-communist policies on urban regeneration, with negative consequences, risk potential and derelict landscapes threatening the local urban welfare. Therefore, these marginal places request further enhancement urban policies to reduce their negative results claiming for more attention by the side of local governments.
