Nowadays revolving stages are com- monplace for operas and musicals throughout the world. With a diameter of approximately 18 metres, the new revolving stage in the Kabukiza Thea- tre is roughly the same size as its pre- decessor, but four times deeper and therefore provides more space for all of the required technology. At a height of 16 metres it is as high as a four-sto- rey building and weighs around 360 tonnes.
