BALI, Indonesia (AP) — An archaeologist says a structure that is believed to be the remains of an ancient Hindu temple has been unearthed on Indonesia’s resort island of Bali.

Wayan Swantika of the local archaeology agency says workers digging a drainage basin last month in eastern Denpasar, Bali’s capital, at first discovered a large stone about three feet underground.

Excavation teams have since uncovered a 62-yard structure believed to be the temple’s foundation.

The find is still being analyzed, but given the shape and characteristics of the materials used, Swantika believes it was built sometime between the 13th and 15th centuries. He added that it is also thought to be the largest ancient temple ever discovered in Bali.
