La Seine Musicale

Île Seguin - 92100 Boulogne-Billancourt Boulogne-Billancourt
In harmony with its natural environment, La Seine Musicale was conceived with respect for the environment in mind. Its extraordinary aesthetic playing on reflections in water gives it a unique identity, that of a veritable concrete ship of 36,500m². Perched on the Seine, the auditorium and its wooden hull seem to float on the river while the mainsail, adorned with more than 1,000m² of solar panels, follows the course of the sun.
La Seine Musicale has over 2,500m² of rehearsal and recording space as well as space dedicated to the Insula Orchestra.
Accessible to all, it is also presented as a place of wellbeing, to visit and to walk in.
By organizing your professional events in La Seine Musicale's show spaces, you are choosing environmental technology, a symbol of our entry into a new era.
A personal advisor, assisted by a team of experts, will accompany you at every stage of your project.
