Abstract: Among Polish sites on the World Heritage List, there are two important towns - Warsaw and Krakow. The great difference between these city is in their history. Cracow is a great Town of medieval history with numerous historic monuments. In case of Warsaw we have a great history behind reconstructed monuments, for comparison. Between those sites is interesting, because there were two different approaches to the question of history presentation and monuments maintaining.
Until the end of the XX century most efforts and activity was spent to restoration and conservation of individual monuments. History presentation was limited to the out fashion exhibitions in historic museums. Such situation resulted in degradation of knowledge and importance of those World Heritage sites. Fortunately, in the last decade, new presentation projects were completed. These projects considerably changed the situation, contributing to this issue.
The main purpose of this paper is to present contemporary presentations of the history of using the latest technological systems, in the era of sustainable development, for examples Warsaw and Krakow. In Cracow the market square the Underground museum was open. In Warsaw restored preserved medieval cellars for cultural purposes and very interesting is a project of a special exhibition called Interpretation of the Monument, being completed lately. The new projects and exhibitions responding to contemporary problems of communication world heritage and the fight against degradation of these places.
