B-51 Cultural Society (KUD B-51) is a non-profit cultural organisation founded in 1991 in succession to Club B-51, a venture of a group of young students engaged in alternative culture established in 1988. The Club was located in a renovated underground shelter at Gerbičeva 51b. Since its inception KUD B-51 has been engaged in the development, organisation and promotion of contemporary art and culture, mostly as an independent producer of performing arts (theatre and contemporary dance) and also an exhibition organiser. It organises the Ex Ponto International Festival and the Kluže Ambient Festival at the Kluže Fortress near Bovec. B-51 (Ex Ponto) is a member of the New European Theatre Action (NETA) and since November 2007 the seat of the NETA Secretariat.
