Nagardhan Fort

The Ancient Throne of Nandivardhan: Vakataka Queens to Bhonsle Sovereigns

situated in the historical countryside of Vidarbha just 6 km south of holy Ramtek hill in Nagpur district, Maharashtra, **Nagardhan Fort (नगरधन किल्ला)** stands upon the sacred ground of ancient **Nandivardhan**—the illustrious 5th-century CE capital of the **Vakataka Dynasty**. Under the remarkable **Queen Regent Prabhavatigupta** (daughter of Gupta Emperor Chandragupta II Vikramaditya and Queen of Vakataka King Rudrasena II), Nandivardhan served as the administrative and cultural hub of central India, where classical Sanskrit literature, Shaivism, and Vaishnavism flourished.

In the mid-18th century, **Raghuji Bhonsle I (1739–1755 CE)**, the founder of the Maratha Bhonsle Kingdom of Nagpur, recognized the strategic location of the ancient mound. Raghuji constructed the present brick-and-stone fortress to serve as a military cantonment and treasury outpost safeguarding the fertile agricultural routes connecting Nagpur with Chhattisgarh and Bengal.
