22.86 x 11.43 x 11.43 is an artistic dialogue developed between Matteo Bettini and Sonia Górecka since 2023, reconstructing and exploring the history of a vanished stone at the foot of Mottarone in the Italian western Alps.

Once a natural landmark and sacred place, the massive stone, measured around 1889 at 22.86 meters wide, 11.43 meters deep, and 11.43 meters high, was gradually dismantled over the course of the last century for the extraction of the precious pink granite from which it was made. Today, all that remains is its name on the map, fragments left from the cutting process, and a void in the collective memory.

The stone in question was not just any rock, but an erratic boulder, a "wandering" stone. These enormous formations differ from the terrain on which they rest, evidence of their displacement across vast distances over time. Before the development of modern geology, their origins remained unexplained, inspiring myths and stories among those who encountered them.

Located in the strip of land between Lake Orta and Lake Maggiore, the place where the boulder once stood lies only a few kilometers from Baveno and Montorfano, historic granite quarrying centers that experienced rapid tourism development from the late nineteenth century onward. The story of this boulder exemplifies the changing meaning of landscape: from an unknown place of imagination to a measurable space with extractable value.

Our first encounter with the boulder was informal, almost accidental, born from a cartographic misunderstanding: when a name on a map does not correspond to what it promises to reveal. This website acts as a trace of the project, opening possibilities for connection, shared reflection, and artistic exchange with others.

Erratic boulders carried by Alpine glaciers were once a common sight across this landscape. This specimen, photographed a few kilometres from the destroyed one, still bears the cut marks left by those who sought to extract its material. (2021)
