The Castle.
I wanted the castle to look like Wawel Castle. I found some really old drawings of it and tried to copy them. Then I decided that any castle will do and the higher on the mountain it is the better. As there still need to be a dragon cave underneath. So my favourites were castles in Czorsztyn, Niedzica and Sandomierz.
