Located 18 km north of Gaya in the Jehanabad District of Bihar.
Consists of four caves including Lomas Rishi, Sudama, Karan Chopar (Nigoha-kubhaor Banyan Tree Cave) and Vishva Zopari.
The caves fall under three categories, Nagarjuniya caves, Pandava caves and cottage - shaped hut caves.
They are carved out of huge granite rocks, and two of them are in the form of a plain rectangular outer hall.
Each cave carries Buddhist inscriptions and houses. These caves look as if they are cut with a laser.
Used by ascetics from the Ajivika sect, these caves were founded by Makkhali Gosala.
Were an influence to future South Asian rock-cut architecture.
Oldest surviving rock-cut caves in India from the Mauryan period (322 – 185 BC).
