Built with massive undressed stones fitted together, this wall is popular for its similarities with ancient Greek walls.

The ancient city of Rajgir was the capital city of King Bimbisara and his son Ajatshatru who were contemporaries of the Buddha. The traces of a fortified wall are found around the city. This wall was built with massive undressed stones fitted together having width of about 14'. It is popularly called as the Cyclopean wall for its similarities with ancient Greek walls. Bastions were built at intervals to strengthen the wall. According to Pali texts there were 32 large gates and 64 smaller ones to enter the fortified city. A considerable part of this ancient massive wall running up along the Ratnagiri hill is still there, starting from the base of the hill towards the hillside.

The foundations of the New city erected by either Bimbisara or his son Ajatasatru can be seen while going to the Bus stand.
