Theater Square Performances is a project in Civilization VI. It becomes available after building a Theater Square district (or one of its replacements).
A city-wide art festival starts, centered on the local Theater Square. The empire's artists, musicians, and writers arrive to perform, converting 15% of the city's Production output to Culture. When completed, it yields Great Writer, Great Artist, and Great Musician points each equal to approximately 11% of the Production invested in it (on Standard speed).
