There is a housing estate in Katowice a called "Stars". It's just a couple of blocks of flats built in the years 1970-1978, pretty mundane, nothing seems to be "starry" in them at first sight... Approximately 6.500 people live there. If you want to see why they are called what they are, have a look at the satelite view (at google maps). And here you'll find more pictures.
