Ecokathedraal

The Ecokathedraal is a work of art made from stacked stones and construction materials that spreads across a large site woven together with plants and wildlife spaces. The structures are built without machinery or cement and naturally integrate into the surrounding landscape.

An artist initiated this project in 1965 using waste materials from local demolition sites to create art without industrial technology. This experimental undertaking is designed to run long-term while systematically observing the interaction between human work and environmental change.

The place embodies a philosophy that treats human creation and natural processes as equal partners, with volunteers actively shaping its ongoing development. Visitors witness how nature and craftsmanship influence and transform each other.

The site is accessible during daylight hours with free entry, walkable on marked paths through the art installation. Parking is located some distance away, so allow time for a short walk to reach the entrance.

The project is intentionally planned until the year 3000 to document environmental changes over extended timescales. This long-term perspective makes it one of the longest-running experimental art endeavors ever created.
