Possible areas of Brennenburg Castle

[Slanderous]

Actully, Altstadt can be located somewhere in my country nearby Baltic Sea, Poland. There is a very small village called "Małe Miasto" and in english it says "Old Town". In german its called "Alt Stadt". I remember these terrains weren't part of a Poland but they were included in Germany and also there are some other things telling us it's somewhere near Baltic Sea. These are only my guesses.


As always, sorry for my shitty english!
