Kraton Ratu Boko is one of the fascinating ancient palace complex in Yogyakarta, Indonesia. Unlike the other huge heritage of Borobudur and Prambanan temples, the Ratu Boko was destroyed – only some parts of the palace can be seen as parts of buildings. That is why it is not as famous as the other two temples.
Ratu Boko is an archaeological site known to modern Javanese as Kraton Ratu Boko or Ratu Boko’s Palace. Ratu Boko is located on a plateau, about three kilometres south of Lara Jonggrang Prambanan temple complex in Yogyakarta Indonesia. The original name of this site is still unclear, however the local inhabitants named this site after King Boko, the legendary king mentioned in Loro Jonggrang folklore.
The site covers 16 hectares in two hamlets (Dawung and Sambireja) of the village of Bokoharjo and Prambanan. In striking contrast to other Classic-period sites in Central Java and Yogyakarta, which are remains of temples, Ratu Boko displays attributes of an occupation or settlement site, although its precise functions is unknown. Probably the site was a palace complex which belongs to the kings of Sailendra or Mataram Kingdom that also build temples scattered across Prambanan Plain. The argument was based on the fact that this complex was not a temple nor building with religious nature, but a fortified palace instead which evidence in the remnant of fortified walls and the dry moat as defensive structures. The remains of settlements also founds in Ratu Boko vicinity. This site is located 196 m above the sea level, on the highest point in the site, there is a small pavilion from which one will be able to see a panoramic view of Prambanan temple with Mount Merapi as the background.
