Cyclopean Wall in Bihar

There is a famous cyclopean wall in Bihar in India which was built in Rajgir. It is 40 km long. The wall encircled ancient Rajgir.

It was built of massive undressed stone carefully fitted together. It is one of the few important pre-Maurayan stone structures ever to have been found. Traces of wall still subsist, particularly at the exit of Rajgir to Gaya.
