The Saga is a 24-minute video installation and light show projected onto the facade of San Fernando Cathedral in San Antonio's Main Plaza. Created by international artist Xavier de Richemont in 2014, it depicts the discovery, settlement and development of San Antonio, and is shown all year round every evening of the week except Monday. Visitors can brush up on local history, or simply enjoy a dazzling kaleidoscope of colour that covers 7,000 square feet (650sqm).
