Ljubljana’s Castle Rat

Friderik is the castle prison rat. Although he shares his name with Emperor Frederick III of Habsburg, who erected the fortress on the Castle Hill, he has in fact lived here much longer. He knows all of the castle secrets and every castle stone. If you meet him, he can tell you many interesting stories or give you an idea for an attractive gift from the Castle Shop.



In fact, I’m Friderik the First, because I’m always the first. I was the first in the battle ranks against castle invaders. During Napoleon’s time, I was the first in Ljubljana to learn French kissing. I got on well with Emperor Frederick III. When there were still dungeons in the castle, I lived there because it was where I could find the best company. I enjoyed the adventures of Erasmus Lueger, the stories of Ivan Cankar, and so on. In exchange, I told them about everything I heard during my wanderings in the castle rooms and under the tables of the castle feasts. Would you like to know these stories too?

Come and visit me!
