Chittoor district of Andhra Pradesh is most famous now- a- days for Tirupati Balaji Temple but it has been a treasure trove of various tools giving ample proofs of development of human civilization from prehistoric times. Archaeologists have discovered various tools and proofs of pre-historic ages ranging from Palaeolithic period (Tirupathi, Sitarampeta, Ellampalle, Mekalavandlapalle, Piler, etc.) to Mesolithic times (Chinthaparthi, Moratavandlapalle, Aruvandlapalle, Tirupathi etc.) to Neolithic and ancient periods (Bangarupalem). The existence of megolithic culture was revealed by the discovery of burials at Irulabanda, Bapanatham, Voyalpadu, Sodum, Velkuru, Nyakaneri, Basinikonda, etc.
