The Barabar Caves are the oldest surviving rock-cut caves in India, mostly dating from the Maurya Empire (322–185 BCE), some with Ashokan inscriptions, located in Makhdumpur Block of Jehanabad district, Bihar, India, 24 km north of Gaya.
These caves are situated in the twin hills of Barabar (four caves) and Nagarjuni (three caves) – caves of the 1.6 km distant Nagarjuni Hill sometimes are singled out as Nagarjuni Caves. These rock-cut chambers date back to the 3rd century BCE, Maurya period, of Ashoka (r. 273–232 BCE) and his grandson Dasharatha Maurya. Though Buddhists themselves, they allowed various Jain sects to flourish under a policy of religious tolerance.
