Candi Kedaton, Hindu temple ruins in Tiris, Probolinggo Regency, Indonesia

Candi Kedaton in Andung Biru village, Tiris, Probolinggo, East Java, is a base or platform structure of andesite stone facing northwest, toward Mount Semeru or Mount Hyang. Its walls carry three relief stories carved on nine panels per side: Arjunawiwaha on the left, Garudeya at the back and Samba on the right. The largest visible element is a rectangular building foot measuring 12.60 by 9.50 metres.

Candi Kedaton in Tiris, Probolinggo, is linked to the Pandanlaras kingdom, a subordinate of Majapahit. Finds of Chinese ceramics from the Yuan (13th–14th century) and Ming (14th–17th century) periods indicate the site was built at least in the 13th–14th century. Excavation revealed overlapping structures beneath a mound topped by Sumur Upas and a small passage.

Locals also call the site Candi Sumur Upas, after a well here: a man who entered it is said to have grown weak inside, hence the name "poison well". Excavation of the earthen mound revealed overlapping structures, and finds include pottery, a headless statue, andesite sculpture, Ming and Yuan ceramics, coins and a human skeleton.

The site is best explored on foot, though the ground between structures can be uneven, so wear comfortable shoes. A morning visit helps avoid the midday heat, which can be strong in this part of Indonesia.

The site is also called Candi Sumur Upas, after a well there. According to local account, someone once entered the well, felt weak inside, and the place became known as Sumur Upas, the poisoned well. Excavation later revealed overlapping structures beneath the mound.
