Nagardhan fort is located around 5 kms from Ramtek. This place is considered to be the first capital of the Vakatakas. Vakatakas build their palace at Mansar. This was confirmed with excavations done from 1998 to 2005.
Nagardhan was originally known as Nandivardhan. According to locals, there is a secret cave from Ramtek Temple to this fort.
Most of the original structure is missing - but Maharastra state government has been working towards restoring the fort.
