The birch forest is the symbol of La Grange au Lac. Thought up as a nod to Mstislav Rostropovich, to whom the venue is dedicated, it was developed from the initial intuition of the architect Patrick Bouchain, who first had the idea to retain a few trees actually inside the building. That approach was not possible in itself, but the idea matured in another way, in the form of a forest recreated at the back of the stage, with a set of mirrors enhancing the visual effect. Today this gives the décor a unique intensity, contributing to its distinctive character, unique and magical, in essence the soul of La Grange au Lac. 

The chandeliers are an integral part of La Grange au Lac, and one of the elements that gives the venue its identity. Their crystal silhouettes contrast with the simplicity of the surrounding wood: a touch of luxury that adds to the venue's magic.

The vast aluminium shell suspended from the ceiling is not just there for the aesthetics. Above all, it has a purpose, that of giving La Grange au Lac its unanimously lauded acoustics.

On La Grange au Lac's walls, certain words can also be found in Cyrillic. This detail is a discreet nod to the cellist Mstislav Rostropovich, to whom the venue is dedicated, and his homeland of Russia. It bears witness more broadly to the venue’s openness to the world, hosting the leading artists on the global classical music scene.
