The idea of creating a light installation in the Mont Blanc Massif was born in 2017.
In 2019, the project was informally presented to a few Chamonix Mountain Guides.
Bolstered by their enthusiasm, a first exchange took place with Chamonix city councilors in July 2020.

In September 2020, authorization was given to carry out a large-scale test in situ, in the high mountains.
The exciting results were incorporated into a project brief released in November 2020.
In September 2021, we were invited by the Mayor to present the project to the committee of elected officials.

Despite the enthusiastic reception, no firm commitment was made at the time.
It was then decided that the project, until then shrouded in a secrecy, should be unveiled.

A public “work in progress” presentation is planned to take place at the Verbeke Foundation in Belgium in 2023.
In parallel, work continues on various aspects, such as technical development and financing.

Since 2019, a growing number of professionals have joined TRIANGLE.
Currently, a core team of 20 people contributes to the progress of the project and more than 150 people regularly follow its development.
