There is no shortage of folk heritage and festivals in our region. Urban and rural communities punctuate their lives with colourful festivals, traditional celebrations, and numerous small examples of living heritage and folklore. Saints' days are marked not only by special masses but also with cultural and folkloric festivals such as that of the Assumption in Nova Štifta and Kostel in August. Among the numerous annual festivals are Osilnica's "Petruvo" in June; the fair of wooden ware and pottery in Ribnica at the beginning of September; the "Pust" Carnival in Dobrepolje and Cerkno in February; and the Mask Carnival in Cerknica and Ribnica. The Cerkno Museum has a magnificent collection of "Pust" masks and costumes. Legends are associated with St. Barbara in Loški Potok and Idrija, with the waterfall near Kostel, a giant in the Ribnica valley, and of the witches of Slivnica.
