Very nice. It reminds me Minimundus in Austria a bit. Itīs an outdoor "gallery" of scale models of many known buildings. The miniatures are built as realistically as possible with attention to detail (they are built from original materials where itīs technically possible). There is a railway with trains there too. I was amazed when I visited the place. If you someday happen to be in Austria near Klagenfurt I highly recommend visiting it.
