On 7 November at Besenval Palace Solothurn An extraordinary moment was experienced with the official opening of the museum « Der Kleine Prinz und Seine Welt » Dedicated to the Little Prince through the collection of Jean-Marc Probst. The event took place in the presence of Olivier d’Agé, nephew of Antoine de Saint-Exupéry and president of Succession Saint-Exupéry d’Agé, which also included the Little Prince Teams and the Antoine de Saint-Exupéry Youth Foundation.


This new museum builds on the remarkable collection collected over more than forty years by the Jean-Marc Probst Foundation for The Little Prince, bringing together more than ten thousand books, objects, documents and rare editions related to the literary masterpiece published in 1943. This collection, one of the most important in the world, is now accessible to the public with particularly successful landscapes created by Batisseurs de Mémoire in a historical setting.

The Little Prince is a universal phenomenon. Translated into over six hundred languages and dialects, it is the most translated book after the Bible. ,With The Little Prince, almost the entire world lives in Solothurn,” The cantonal chancellery reminded when the project was announced.


Jean-Marc Probst, an enthusiastic collector since 1980, has patiently brought together volumes from around the world. His Foundation also enriches the legacy of the work by supporting new publications since 2013. This new cultural venue will continue to preserve and share the humanist message of Antoine de Saint-Exupéry through educational and interactive content designed for children as well as adults.




Located on the banks of the Aare, the Besenval Palace, built at the beginning of the eighteenth century, opens a new chapter in its history as it becomes a space dedicated to imagination, sharing and encounters inspired by the Little Prince.
