Grand Hall

Großer Saal mit ansteigender Reihenbestuhlung


The Grand Hall of the RHEIN SIEG FORUM provides 1200 sqm of space with a capacity exceeding 1,400 seats in rows. It can accommodate 2,600 people without seats. Thanks to its gallery and the option of ascending rows of seats, the Grand Hall ensures outstanding all-round visibility. Acoustic partition walls transform the Grand Hall into several rooms that can be used independently of each other.

Modern equipment, sleek architecture, stylish foyers, adjustable floor system with lifting platforms, high-quality parquet flooring, natural light or completely darkened - the Grand Hall provides the perfect setting for almost any event.
