About 45 interested people from all over the country took part in the fourth edition of the Le Roy walk from Heerenveen to Mildam and back to Heerenveen on Sunday, June 14, 2026.

The walk, organized by the TIJD Foundation, passed by various places closely connected to the life and work of ecotect Louis Le Roy (1924-2012) and his wife Inge Le Roy.

An important stop was the Le Roy Garden in Heerenveen, where participants were introduced to one of the most accessible examples of Le Roy's philosophy. In this garden, man, nature, and time work together on a constantly changing landscape. The walk then continued past the former home of Louis and Inge Le Roy in Oranjewoud to the Ecocathedral in Mildam, where the participants had lunch together.

Along the way, extensive attention was paid to Le Roy's vision on the relationship between man and nature. In his ecocathedral projects, the focus is not on the end result, but on the process of continuous development. By giving space to spontaneous growth, biodiversity, and human involvement, landscapes emerge that continue to develop over many generations.

Interest in the walk was greater than during previous editions. The participants came from various parts of the Netherlands and engaged in conversation along the way about nature development, ecological thinking, and the significance of Le Roy's work for current issues concerning the living environment and sustainability.

"It was remarkable to see how many people are still inspired by the work of Louis and Inge Le Roy," said organizers Henriette Le Roy and Peter Wouda . "For some, it was a renewed acquaintance with the ecocathedral projects, while others visited these special places for the first time. The wonder at what has been created here over decades was clearly visible in many participants."

The organizers hope that the walk invites visitors to also visit the Le Roy Garden in Heerenveen and the Ecocathedral in Mildam on their own. Both locations are living examples of a way of thinking in which time is not seen as a limitation, but as a creative force that connects nature and culture.

With activities like this, Stichting TIJD draws attention to the unique cultural, ecological, and landscape heritage left behind by Louis and Inge Le Roy in Heerenveen, Oranjewoud, and Mildam.

  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)
