Gunung Padang is a megalithic site located in Karyamukti village, Cianjur regency, West Java Province of Indonesia, 50 km southwest of the city of Cianjur or 6 kilometers from Lampegan station. It has been called the largest megalithic site in all of Southeastern Asia, and has produced carbon dating results which, if confirmed, suggest it is extraordinarily old.The survey believes that Gunung Padang was built in four different eras.
Located at 885 metres above sea level, the site covers a hill in a series of terraces bordered by retaining walls of stone that are accessed by about 400 successiveandesite steps rising about 95 metres. It is covered with massive rectangular stones of volcanic origin. The Sundanese people consider the site sacred and believe it was the result of King Siliwangi's attempt to build a palace in one night. The asymmetric Punden Berundak faces northwest, to Mount Gede and was constructed for the purpose of worship. Based on various dating techniques, the site was completed by 5000 BC and quite likely much earlier.[4
