 Important churches and the castles, testimonies of the early Polish culture before the German colonization in the 13th and 14th century, were preserved, palaces and manors however were neglected, vandalized and sometimes destroyed.Directly after the war the reactivation of tourism was tried, however as most holiday homes in the valley were occupied by new settlers and the touristic infrastructure was in a sorry state these attempts failed.The parks, the excellent hiking trail network and erstwhile view points run to seed, while most of the art collections were either destroyed or dissolved and spread all over Poland.
