Louis Le Roy (Amsterdam1924 – Oranjewoud 2012) eco-tect, artist, writer, educator and Professor honoris causa has been working for more than thirty years on an enormous structure in a meadow at the Friesian settlement of Mildam near Heerenveen. There, on a two-hectare site, he piled up with his bare hands paving bricks, paving stones, kerbstones and other discarded street rubble while allowing nature to proceed about him unhindered. Le Roy calls this fascinating jungle populated by large stacked edifices an Eco-Cathedral. Inspired by the Nobel Prize-winner Ilya Prigogine, Le Roy pondered the following question: ‘ What can one person achieve working with nature in space and time?Le Roy’s position on the concepts of space and time was at odds with the often rapid, super-efficient, function-hugging approach to greenspace and nature in the Netherlands. The Eco-Cathedral is a place where time regains space and space regains time. So the project he began is expected to be continued by others at least until the year 3000.” In 2004, as a gift for his 80th birthday, the ‘Time’- foundation invited Moeno Wakamutsu to perform a dance on the site.
