For an exhibition in Heerenveen in 1996, Le Roy explained on a number of A4 sheets what an ecocathedral is, what you can use to build one, and why we need to build one.
Years later, when a semi -permanent exhibition about Le Roy was organized by Minji Choi at the Nieuwe Instituut in Rotterdam, these texts were carved in stone and exhibited. After more than two years, the exhibition was closed, after which the stones found their way to the ecocathedrals in Mildam and Heerenveen. There, they will be given a permanent place.
In the Le Roy garden, one example has now been installed, in which Le Roy briefly but powerfully explains what an ecocathedral is. The other three examples are located in the ecocathedral in Mildam.
What is an ecocathedral?
An ecocathedral is a structure:
- that arises as the product of a lifelong collaboration between natural organisms:
- plants - animals - people - that is realized exclusively with the aid of energy supplied by natural organisms:
- free energy - that will have to develop into a highly complex structure in a completely natural way:
- development in space and time - whose final form is not determined in advance—by means of drawings or models:
- spontaneous creation
