A 9th-century Buddhist temple
South of Prambanan. The ruins of a large palace or temple, located on a hill 200 metres above the Prambanan plain. The origin is uncertain, but is popularly described as the palace of King Boko from the Prambanan legend. The hilltop has a viewpoint of Prambanan that is popular at sunset, and makes for good pictures using a zoom lens. A series of pools suggests palace bathing quarters. Only building foundations remain and it's difficult to make sense of the sprawling site, and the available guides may not speak English. Ratu Boko is incorporated into the Borobudur Park Authority, but entry is separately charged >10 years old: US$25, aged 3 to 10 US$15. There is a combined ticket with Prambanan that saves a few dollars.

Candi Rara Jonggrang
It is the largest and most-visited of the temples just to the left of the main entrance. While there were 237 temples built, most have long since crumbled and the main remaining attractions are the six temples of the central court, richly decorated with carved reliefs. Three of them, known as the Trimurti ("three sacred places"), are particularly important. About 2- 4-hr visit if doing all temples and museum.
North of Candi Lara Jonggrang is a poorly displayed museum laid out in a series of small houses connected by walkways. Explanations are minimal, mostly only Indonesian text, but entry is free so you might as well take a look.
