The ruins are located on a riverbank, 200 meters away from the Hindu temple. Ngempon stands on the other side of the river, close to hot and cold springs.
Wahyu, an official from the Center for Preservation of Cultural Heritage, who came to the location, said the newly discovered structure was believed to date back to the eighth century.
Nurkholis, a local resident who found the structure, said, “I immediately reported the finding to a worker restoring Ngempon Temple. He told me to stop digging until an official from the center arrived.”
