Participants from Turkey and countries such as the Netherlands, Belgium, Germany and TRNC other than Eskişehir are participating Festival of Thought- Provoking Fairy Tales, which is being held face-to-face and online every year in November since 2019. While Fairy Tale Castle brings hundreds of people together with different disciplines such as yoga, ecology, play, drama, science and art in the magical world of fairy tales, the realities of the fairy tale world and the world we live in are compared, and the thoughts that are emphasized in the fairy tales, that are not mentioned or that take place between the lines are questioned through activities.

The programs in the Festival of Thought- Provoking Fairy Tales which are organized under the guidance of the author Dr. Nilay Yilmaz, are prepared taking into account the World Children's Book Week, Children's Rights Week, World Freedom Day, World Philosophy Day, World Tolerance Day, World Game Day, World Origami Day and World Drama Day, which are celebrated in November.

The Festival of Thought- Provoking Fairy Tales aims to build a bridge between the past and present.
