The restoration of Polish cities from WW2 destruction [123]
Why? Klotzkos old town was partly destroyed between 1959 and 1970 due to subsidence damages, which the new owners of the town didn't correct at an early stage.
I asked because originally I thought you were Polish, and then you jump up with Klotzko :) now I am not that surprised you couldn't read a forum discussion in Polish (I mostly can't read forums in German so you are excused)
as for destroying German cultural objects say monuments - hmm I'm pretty curious how do you imagine Polish population walking past all those Frederick the Greats, Keiser Wilhelms and Hindenburgs on a daily basis in the post war years
as for the cemeteries - various cemeteries had various stories - some still do exist (there is a big old evangelical cemetery in Opole for example, Wrocław Jewish cemetery has been left intact too (maybe because it was Jewish - it is a museum now AFAIK))
it is true you won't find too many German graves - i know cemeteries not in use anymore where the monuments/graves were razed -
some German cemeteries have been 'recycled' in a way (however nasty it may sound to you) like the big cemeteries in Wrocław - I don't know if they were emptied of German monuments before they started to fill with Polish graves (graves on big cemetries in big cities are 'cleared' anyway after 25 years in Poland to give place to new burials (unless you pay a considerable fee to let them stay longer)
