The mysterious and mighty Slovenj Gradec has always attracted outstanding craftsmen, sculptors, painters, musicians, writers, heroes … and we even had Pope Pius II here as a young parish priest. It’s no wonder that there is a misterious sign in the middle of the city: “the center of the world”. Strange is the unusual dusty thing we found in a former coin mint. It’s a mysteriously locked book that has a special energy. We managed to open the first page … and then we ran out of courage? Will you be the one who will explore what kind of message the book is carrying, get to know the hidden history of the city and above all have great fun doin it?
