Andy Goldsworthy is an internationally-renowned artist of the Land Art movement, who has created works throughout the UNESCO Geopark Haute-Provence territory.

In 1998, for the Promenade Museum, he created 5 “water cairns” that accompany visitors along an access path (sentier des cairns).
The water circulating inside the hollow cairns is audible and invisible, like the water in the Promenade Museum: it’s everywhere, even when you can’t see it.
Each cairn is an echo chamber amplifying the sound of an underground stream connecting them.
The first cairn, by its silence, announces the mystery that is revealed by the final cairn.
