Bada Valley Megaliths

Located in Lore Lindu National Park, Central Sulawesi, Indonesia, the Bada Valley Megaliths comprise hundreds of ancient stone statues called watu ("stone") in local Badaic languages and arca ("statue") in Indonesian [1]. Dating to 4500–3000 BC, these monumental sculptures remain shrouded in mystery, with their purpose and builders unknown [1][2]. First discovered in 1908, the megaliths represent one of Southeast Asia's most enigmatic prehistoric artistic traditions [2][3].
