There have been numerous discoveries of megalithic sculptures in Indonesia. Subsequently, tribal art has flourished within the culture of Nias, Batak, Asmat, Dayak and Toraja. Wood and stone are common materials used as the media for sculpting among these tribes. Between the 8th and 15th centuries, the Javanese civilisation has developed a refined stone sculpting art and architecture influenced by Hindu-Buddhist Dharmic civilisation. The temples of Borobudur and Prambanan are among the most famous examples of the practice.
