Batujaya is an archeological site located in the village of Batujaya, Karawang in West Java, Indonesia. The site is five square kilometers in area and comprises at least 30 structural in what Sundanese call hunyur or unur (high mounds of earth consisting of artifacts). Unur is similar to the manapo found at the Muara Jambi archaeological site.
The site was first found and examined by archaeologists from the University of Indonesia in 1984. Excavations have since uncovered 17 unur, of which three are in the form of pools. The structures found are made of bricks composed of a mixtures of clay and rice husks (vajra-lepa), not volcanic rock which is difficult to find in Batujaya. Two structures recovered are in the form of temples, one of which, known as Jiwa Temple, has been restored. According to Dr Tony Djubiantono, the head of Bandung Archeology Agency, Jiwa was built in the 2nd century.
As local Indonesian governments do not maintain the site, Ford provides funds for research and excavation of the Batujaya complex as part of its Conservation and Environmental Grants.
The discovery of this archaeological site was important as although it was the location of Tarumanagara, the oldest Hindu-Buddhist kingdom in Indonesia, West Java lacks ancient temple remains. Before the discovery, only four temple sites have been found in West Java, namely they are Cangkuang temple (in Garut), Ronggeng Temple, Pamarican Temple, and Pananjung Temple (in Ciamis).
