What is the area above the stage called where scenery and actors are flown in using pulleys?

The area above the stage where scenery and actors are flown in using pulleys is known as the flies. This region consists of a system of ropes, pulleys, and counterweights that allow for the smooth operation of curtains, backdrops, and various stage elements being raised or lowered as needed during a performance. The design of the flies enables quick changes and adjustments, which are essential for theatrical productions.

While the deck refers to the stage floor itself, the loft typically refers to the space above the stage that may house equipment or support structures but does not specifically indicate the system for flying in scenery. The gridiron, although relevant in theatrical structures as a support for the rigging, has a more technical architectural meaning and does not focus specifically on the functionality of moving stage elements. Therefore, flies is the most accurate term for the area designed for this purpose in a theatre setting.
