The Embassy of the Free Mind is not just a place where knowledge is shared – it is also a community. We fulfil our mission thanks to our growing network of supporters, volunteers, and team members, all of whom make this museum what it is: a place that makes universal wisdom accessible to all. 


Join an International Network of Universal Wisdom:

Support Us


Your support helps us not only preserve our unique book collection of the Bibliotheca Philosophica Hermetica for future generations. It also funds our plans for growth, including infrastructural renewals and programmes that enhance the interaction with continuously evolving knowledge.  

By becoming a donor to the museum, you will become part of a community that celebrates the boundless nature of universal wisdom, weaving an ongoing tapestry for the generations to come. It opens the doors to you here at the House with the Heads, making you a part of our ever-expanding network of people dedicated to the ancient (and newfound) knowledge that lies within these walls.
