In many small towns of Mazovia Region (Poland) medieval castles act not only as an attraction for numerous tourists, but also can be a chance for various cultural and education initiatives, focused on city’s permanent inhabitants needs. These architectural monuments might be for example attractive for certain local community both as a possible location of city cultural/education centre and as an important symbol of regional identity (its history and tradition). The problem is to find a well-balanced compromise between castle’s multifunctional use (museum, cultural centre) and specific requirements of different groups of its visitors (tourists and local community members), without destroying the specific character of the unique, historic environment. That issue becomes crucial, as a rational proposal of castle’s revitalization (with a balance between commercial development, tourism requirements, local community expectations and historic preservation needs), treated as one of the elements of spatial planning intended to create sustainable urban conservation program, might have an important influence for present and future environment quality of a small town. [Nuttgens P. 1991; Zachwatowicz J. 1982] The main purpose of our research, undertaken in the Institute of Tourism and Recreation, AWF in Warsaw, was to consider some present and future functions of the selected medieval castles located in the small towns of Mazovia Region. In the first stage of this research (2004-2005) field studies (questionnaires) were completed in Czersk (small town near Warsaw), focused on the present function of the castle and expectations of its future program, expressed by local community members. Our first results are answers to the following questions: 1)castle legal and technical state, main functions and its conservatory programmed requirements; 2)tourist movement there (per year); 3)management activity to create both cultural and educative events; 4)cooperation and initiatives of local authorities and non-government institutions; 5)accessibility for handicapped persons; 6)expectations of castle future functions and cultural/educative activities there (as a proposal from the part of the local community representatives). We hope that our research result might constitute an important part of the sustainable spatial planning policy, intended to serve the local community requirements, environment protection, sustainable historic architecture conservation and the small city revitalization needs.
