Abstract: The invention relates to a theatre hall comprising a wall (2) with a circular cross-section formed by several adjacent defining projection surfaces (3) and comprising projectors (6). At least one projector (6) is associated with each projection surface (3). The theatre hall also has a dome-shaped hall ceiling (17) and several projectors (18) are associated therewith. All of the projectors (6, 18) can be controlled by a common control centre unit (15) in such a manner that a merging overall picture is produced on the wall (2) with a circular cross-section and on the dome-shaped hall ceiling (17). The theatre hall further comprises devices (10) for influencing the central control unit (15).
