Introduction: In the past Polish towns and cities have functioned as popular tourist destination, but heritage tourism and especially one of its segments – urban tourism – has grown significantly nly in recent years. As a result of socio-economic transformation, more income, higher levels of education, growing awareness of our country, globalisation process (access to EU) and better tourist infrastructure (transport, accommodation) now we could experience much more bigger tourists interest in our historic cities. Today especially Cracow and Warsaw have been visited by millions of tourists per year. Needless to underline that the main attraction for tourists there are the historic centres of these cities, Old Town in Warsaw and Old Town in Cracow. Research question and methods: As tourism develops in historic centres, it brings with it recognisable ecological, cultural, social and economic impacts. Today the tension clearly exists between users of ‘shared space’, between visitors and residents: those who work and live in and around heritage sites. Our research study (conducted by the author in the Institute of Tourism and Recreation AWF University Warsaw, 2010-2013) was about enquiry the phenomenon of heritage tourism and its impact on Old Town in Warsaw local community members. We were interested both in negative and positive consequences, in revealing socio-cultural impacts that cultural tourism have on historic district residents (host community). One of the important parts of our survey was to identify the role of heritage tourism in Old Town regeneration. We intended to shape our research in form of applied one and hoped to find a solution for sustainable heritage tourism development. To measure these issues from different perspectives we used combination of methods as we have aimed to achieve a balance between quantitative and qualitative approaches: academic studies of published resources and spatial plans (quantitative secondary data analysis) as well as the case study - primary data in form of observations, semi-structured and structured interviews conducted between local community and local authority representatives (Dallen 2003; Finn 2000; Page 2003; Phillimore 2004; Smith 2006). Results and Conclusions: Our research showed that the most important aspects of physical damage at historic properties are wear and tear, litter, pollution, noise and vandalism. Mass of tourists (throngs of people filling narrow streets) and anti social behaviour of tourists were the major disruptions listed by local community members of Old Town in Warsaw. Some residents mentioned the lack of shops with food and very high prices at few groceries which are today in minority among numerous restaurants, banks, fancy boutiques and souvenir shops – targeting with their offer to tourists and much less interested in residents of Old Town group. Sadly very active Association of Old Town Residents (founded in 2000) cannot contribute as effectively in shaping the spatial policy as potentially it could, because most of its members have not legal rights to their apartments. Without clear position they are treated only as tenants of communal properties and as a ‘weak’ partner for Warsaw Municipality and Old Town Local Authority.
