The Arjuna Complex is a small group of Hindu temples on the Dieng Plateau. While it doesn't compare to the impressive towers of the Prambanan, the complex and its associated museum are a worthwhile stop when visiting the plateau. The group are among the oldest temples in Java, with initial construction completed around 809 AD.
A lone temple near the museumThere are four main chapels in the main group, and another one on a hill nearby, where there's also a small museum. Arjuna is actually the northern-most chapel in the main complex, and isn't the original name of the temple. The buildings were all named in modern times after characters from a puppet play.
Admission to the temple complex is included in the 25,000 Rupiah (1.50 USD) combined ticket that includes the Sikidang Crater. Visiting the small museum will cost you another 5,000 Rupiah (0.30 USD). Signs in the museum are in Indonesian only, but there is an interesting video presentation.
