Book "Louis Le Roy, ecotect" by Rob Hendriks and Piet Volaard presented in Heerenveen

On Saturday, October 31, 2026, the book "Louis Le Roy, ectotect" by Rob Hendriks and Piet Vollaard will be presented during the TIJD symposium at De Koningshof in Heerenveen.

It is by far the most comprehensive book on the ecotect Louis G. Le Roy to date. It was preceded by years of research, during which an inventory was first made of all publications that have appeared about Le Roy over the years and the articles he wrote himself. All projects in which Le Roy participated or which are directly inspired by his ideas have also been mapped out. The Le Roy Garden in Heerenveen is also described in detail.

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:

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.
The Time Pyramid of Manfred Laber in Wemdinge, Germany
The Future Library (02014 - 02114) of Katie Paterson in Oslo, Denmark.
The Longplayer at Trinity Buoy Wharf in London, a musical piece that lasts 100 years and has been playing since January 1, 2000.
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)
