The halle400 is a multifunctional events center directly on the west bank of Kiel Bay. The former submarine assembly hanger was renovated and transformed into a modern events center. The potential uses range from concerts, theater, and musicals, to exhibitions and conventions, to celebrations and gala events. The rooms can be used as small, independent units with separate entrances, or as one large event room. The halle400 will be used primarily as a venue for crossover and jazz projects of the Schleswig-Holstein Musik Festival.
