Mariakirken, the oldest building in Bergen, is a more irregular space than Håkonshallen. The "Mouvance I: Mass" concert took place here. I searched for optimal speakers positions, and ended up with similar a setup to what we did in Håkonshallen; 3 speakers in front of the altar, 5 speakers along the side walkways, behind the columns at each side, 3 speakers at the organ gallery. For most seats in the church, some speakers would be behind columns, projecting indirectly.
