Gunung Padang is a megalithic site located in Karyamukti village, Cianjur regency, West Java Province of Indonesia, 30 kilometres (19 mi) southwest of the city of Cianjur or 6 kilometres (3.7 mi) from Lampegan station. It has been called the largest megalithic site in all of Southeastern Asia, and has produced controversial carbon dating results which, if confirmed, would suggest that construction began as far back as 20,000 BCE.
