Discover all our special kids’ activities here.

Welcome to the Embassy of the Free Mind, a meeting place where wisdom from around the world is collected. This wisdom is part of a very special collection of more than 25,000 books: the Bibliotheca Philosophica Hermetica, the library of hermetic philosophy which would make Dumbledore’s mouth water! The books are about many things: the universe, nature and humans beings – in other words: they’re about you! The books are on such subjects as magic, history, philosophy, alchemy, religion and much more. One thing is of central importance in this large collection of books: everything in the universe is connected with everything else. The authors of these books have tried to unravel the secrets of our world (and so of us human beings) each in their own way.

Come and discover some of those secrets on this web page specially designed for kids. 

By the way, have you already downloaded one of our free colour plates from our webshop? Enjoy!


The Embassy of the Free Mind needs your help! 

Our house alchemist, Bolius Bubble Brewer, accidentally drank a potion of oblivion, and now he’s lost all his alchemical knowledge!

Will you help him recover his knowledge? Step inside, and find out about the Embassy of the Free Mind, Bubble Brewer and the secrets of alchemy. Go on a treasure hunt in the virtual museum and look for twelve images that each have a puzzleto solve. Solve them and find the letters of the magical password that will restore Bubble Brewer’s knowledge.

This virtual alchemical treasure hunt has been specially designed for children from the age of 8 (but also for people who are young at heart :-). Start the  treasure hunt here (note: the hunt is in Dutch only). Carefully read the instructions! You can write down the answers on a piece of paper or add them to the special answer page (download HERE). Please note: the treasure hunt works best on a desktop computer and less well on a tablet or smartphone.

Hang on the answers and the password. As soon as the museum is open again, you can bring us the answers and your magical present, with Bubble Brewer’s compliments. 

What are you waiting for? 

We count on you, young alchemists!

Recently we have organised a workshop for children (4-8 years) in which Ankie Hettema explained three Hermetic principles. After a brief conversation between Ankie and a puppet representing Hermes Trismegistus, the children went into the garden to find out more about the connection between science, art and energy. Next they went on a treasure hunt through the museum and were invited to create their own work of art about one of these principles. The workshop was regarded as a great succes.
