Konferencja miedzynarodowa, Wilanów, 15-17 pazdziernika 2008 r.)The titular conference presented the outcome of interdisciplinary research conducted by the National Heritage Board of Poland relating to the park-palace premises of Wilanow (2003- 2008) and its comparison with studies into assorted historical estates in Europe. The participants discussed the Wilanow programme, the technical aspects of its realisation, and the results of architectural, archaeological and archival studies. The outcome of research performed in the United Kingdom was presented by Brian Dix, a specialist in garden archaeology and a consultant of English Heritage, and Dr. Lucy Worsley, curator of Historic Royal Palaces. Other foreign speakers included: Brian Kerr (UK), Moses Jenkins (Scotland), Emanuela Zanda (Italy), Jozsef Laszlovsky (Hungary), and Vlodimir Gerich (Ukraine), as well as Polish researchers collaborating with the Museum Palace in Wilanow: professors Andrzej Koss and Zbigniew Myczkowski together with Piotr Szpanowski. Considerable attention was paid to such issues as methods of treating historical estates, the boundaries between conservation and restoration, and the purposefulness of including archaeological studies into revalorisation programmes. The prime conclusion drawn from the debate was that regardless whether the finally selected method involves conservation or restoration, the decision should be always made with due thought and be based on the results of a meticulous archival survey and complex interdisciplinary studies.
