A unique group of megalithic tombs has been found in Pedda Anupu Chenchu Colony, Palnadu district, Andhra Pradesh. The burials include rare dolmens with sloping capstones, unlike usual flat ones in the Deccan region. This discovery was made by Dr. Sai Krishna Esarapu of the Archaeological Survey of India and Dr. Yadava Raghu from Sri Sathya Sai University. The site is just 100 metres from a Chenchu tribal hamlet and five kilometres from the famous Nagarjunakonda complex. On November 30, 2025, researchers recorded about 60 to 70 megalithic burials here. These include dolmens, cists with stone piles, a stone circle, and a small human-shaped stone about one metre tall. The sloping capstones have the front opening raised while the back lies near the ground, differing from the usual horizontal style. The capstones range from 2.5 to 3.15 metres long. The site sits on ancient quartzite rock around 1.6 billion years old. This rock type likely influenced how people settled and built their tombs in this semi-dry part of the Lower Krishna basin. Nearby, archaeologists found remains of a disturbed Buddhist site with broken pillars and large bricks damaged by farming. This suggests the area was used from the megalithic period through the Ikshvaku-era Buddhism phase, spanning roughly 1200 BCE to 300 CE. The researchers call for more public awareness to protect this important site, which helps us understand ancient local cultures and death rituals.
