Stellenbosch Outdoor Sculpture Trust (SOST) is a non-profit organisation supported by patrons, foundations, and corporations. It brings contemporary art to a broad audience in Stellenbosch by mounting free, annual exhibitions that offer the public powerful experiences with art and the urban environment. Created in 2012, SOST’s primary mandate is to make art accessible to all. Since the first exhibition, the Trust has brought over 250 works of art to the streets of Stellenbosch by some of the world's most renowned artists. SOST is the official art partner of the Art Mile and hosts the Stellenbosch Triennale every three years.
