WOS Festival x SON Estrella Galicia has been held every September, for six years now, gathering a dozen exceptional locations in the city of Santiago de Compostela, all within walking distance from the cathedral, in a historic district protected as a World Heritage Site. The locations include two museums, two theaters, an 18th century church, unique buildings such as Ciudad de la Cultura or the headquarters of the SGAE Foundation, a market, two concert halls and an independent cinema hall, among other spaces destined to create unique experiences for a reduced audience. The event presents an authentic architectural and touristic route through the city, threaded by a program of proposals around risk, exploration, contemporary and digital art, the contrast between tradition and innovation, and the dialogue between disciplines. The program consists of about fifty activities, spread over five days.
