At the TIJD symposium on Saturday afternoon, October 31, 2026, the book "Louis Le Roy, ecotect" by Piet Vollaard and Rob Hendriks will be presented.

For ten years, the authors harboured the idea of writing a book about Le Roy (1924-2012), as no complete publication had appeared up to that point. Although a great deal has been published about Le Roy over the years, and he himself wrote many books (including *Natuurschakelen, natuurschakelen* and *Retourtje Mondriaan*), gathering all the information proved to be a difficult task. Therefore, in preparation for the book, a website was developed to track as many publications, lectures, exhibitions, documentaries, and projects as possible. This Louis Le Roy oeuvre website is largely accessible to the public at www.louisleroy.nl

The book contains Le Roy's life story and includes an inventory of all projects in which Le Roy has been involved, both domestically and abroad. In addition to the ecocathedral in Mildam and the Le Roy area in Groningen, there is naturally also a chapter devoted to the Le Roy Garden in Heerenveen, the ecocathedral that has been under development since 1966.

Other long-term art projects

Various artists have been inspired in one way or another by the long term, also known as cathedral thinking. A number of interesting examples:

  1. The Letters of Utrecht (02000 - as long as there are Saturdays): a poem that is written letter by letter every Saturday in the city center of Utrecht using stones.
  2. The Time Pyramid of Manfred Laber in Wemdinge, Germany
  3. The Future Library (02014 - 02114) of Katie Paterson in Oslo, Denmark.
  4. The Longplayer at Trinity Buoy Wharf in London, a musical piece that lasts 100 years and has been playing since January 1, 2000.
  5. The Tropfenstein machine (01996–02496) with which a stalactite is made in a museum in Hamburg.

" For a proper understanding of what is written, it must always be borne in mind that when nature is mentioned, natural processes are *always* meant, but never nature in its temporary form ." Louis G. Le Roy ( 1924 - 2012 )

" When we build, let us remember that we are building for eternity. Let it not be for present pleasure, nor for present use only; let it be such a work that our descendants will be grateful to us for it ." John Ruskin (1819–1900)
