Batujaya, Archaeological site in Karawang, Indonesia

Batujaya is an archaeological complex with ancient brick structures in Karawang, spread across a large area with rice fields in between. The site contains several temples, with two main ones restored and walkable, along with remains of other structures that excavations have uncovered.

The brick temples were built during the Tarumanagara kingdom, with preliminary research at Jiwa Temple placing construction between the 5th and 6th centuries, based on votive tablets found there. The site was first examined in 1984 by a University of Indonesia team after reports of finds among earth mounds called unur. Excavations from 1992 to 2006 uncovered 31 building footprints, and in April 2019 the complex was declared an Indonesian national cultural treasure.

The name Segaran comes from the Sanskrit word for sea or lake, recalling the pond that once bordered the temples. Votive tablets of clay bearing Buddha images and inscriptions, found in the area, point to Buddhist prayer practices. The site lies in a Hindu kingdom's territory, and the Buddhist complex built there is cited as evidence of tolerance between religions.

Wear sturdy shoes as the ground is uneven and rice fields surround the area. The two main temples are easy to reach, but plan time for slow exploration, especially if mud appears after rain.

The site's name comes from the mounds locals call unur or hunyur, revered as sacred long before excavation began in 1984. Researchers from the University of Indonesia investigated after reports of finds among these earth mounds in the rice fields. Excavations between 1992 and 2006 uncovered 31 building footprints.
