« L’Arsenal » concert hall — Metz

This rehabilitation and requalification operation turns former military buildings, built in the 18th century by the architect Blondel, into a cultural complex housing two auditoriums of 1,350 and 350 seats. Inaugurated in 1989, the halls are devoted essentially to symphonic concerts and dance performances.

Acoustic reverberation reaches 2.3 seconds in the middle of the large auditorium, over a frequency range extending from 125 Hz to 4 kHz, for a volume of 13,000 m³ — close to 10 m³ per spectator.
