French artist Xavier de Richemont’s video installation “San Antonio | The Saga” employs San Fernando Cathedral as a canvas to “narrate the historical discovery, settlement and development of San Antonio” via a 7,000-square-foot projection choreographed to music in surround sound. Opening Friday, June 13 (7-11pm), the 24-minute spectacle will be on view periodically through 2024. For details, visit mainplaza.org.
