Some visitors say this statue fills them with unease, some that it reminds them of the titular characters from the popular game franchise The Assassin's Creed, and others feel it is reminiscent of the scary dementors from the Harry Potter tales.
In truth, however, it is meant to depict a concrete historical figure - the chronicler of the Hungarian king, Béla. This chronicler remained anonymous, hence the statue's hood and hidden facial features.
