The Dieng Plateau Temples are a group of small Hindu Shivaite shrines on a high volcanic caldera floor at 2,000 metres elevation in central Java, Indonesia, built between approximately 750 and 850 CE under the early Sanjaya dynasty — making them among the oldest standing stone Hindu temples in Indonesia. The eight surviving temples of the Arjuna group are square cella structures of dressed andesite blocks with stepped pyramidal roofs and small projecting porches. Dutch archaeologist Hermann Cornelius rediscovered the abandoned and partially flooded complex in 1814; subsequent dewatering work in the 19th century recovered the temples from accumulated lake sediment. Originally the plateau held some 400 small shrines according to early Dutch survey reports. Dieng comes from Di Hyang, meaning abode of the gods in Old Javanese. The plateau still emits sulfurous gas from its active geothermal vents.
The Arjuna group temples stand in two parallel rows on the cleared plateau floor with their steep andesite roofs intact.
