The temple elevation is 410 meters above the sea level. The western hill of Gumuk Ijo overlooks rice paddies, villages and Adisucipto International Airport.
The temple compound measures 0.8 hectares, however the original temple compound is estimated to be far larger. On the hill foot and slopes on western sides there are some archaeological artifacts and temple ruins which suggest the larger compound may exists from the foot ascending to the main temple.

The temple compound consists of several terraces. On the western part some temple ruins were discovered, most of them are being excavated. It was estimated that more than 10 Perwara or lesser temples ruins are still buried in this terraces.
The main temple compound located on the uppermost terrace, consists of a large main temple facing west and three perwara temples on front of it facing east. The three perwara temples was meant to honor Trimurti, the three highest gods in Hinduism: Brahma, Vishnu and Shiva.
