Two sandstone hills facing each other across a saddle, hollowed out more than two thousand years ago into cells for Jain ascetics. Udayagiri holds eighteen caves, Khandagiri fifteen, and the carving along their verandas — elephants, dancers, a king's victories — is among the earliest figurative sculpture in eastern India. The Hathigumpha inscription on Udayagiri records the reign of Kharavela of Kalinga in a Brahmi script that is read aloud by scholars still. Late afternoon brings local families up the steps and monkeys down from the trees.
