Agreed. By the way, Google Berlinka Art Collection.Beautiful spots indeed.
As for German culture, well, Poland has felt the impact of German culture quite deeply...
[Nazi plunder] "After the occupation of Poland by German forces in September 1939, the Nazi regime attempted to exterminate its upper classes as well as its culture. Thousands of art objects were looted, as the Nazis systematically carried out a plan of looting prepared even before the start of hostilities. 25 museums and many other facilities were destroyed. The total cost of Nazi theft and destruction of Polish art is estimated at 20 billion dollars, or an estimated 43% of Polish cultural heritage; over 516,000 individual art pieces were looted, including 2,800 paintings by European painters; 11,000 paintings by Polish painters; 1,400 sculptures; 75,000 manuscripts; 25,000 maps; 90,000 books, including over 20,000 printed before 1800; and hundreds of thousands of other items of artistic and historical value. Germany still has much Polish material looted during World War II. For decades there have been mostly futile negotiations between Poland and Germany concerning the return of the looted property."
