Dominating the Solo plain from 900m above sea level and the last stronghold of Hinduism in Central Java, Candi Sukuh (15C) was devoted to the worship of a mysterious hero. This break with orthodox Shivaism explains the unusual iconography, such as the phallic symbols, the large altars shaped like flat tortoises, and the outer bas-relief decoration depicting Bima and Sadewa, the heroes of the Indian Mahabharata in purely Javanese episodes. Six kilometres away is Tawangmangu Waterfall.
