Krishnagiri Fort is a historical fortification located in the Krishnagiri district of Tamil Nadu, India. The fort is situated on a rocky hill in the town of Krishnagiri and is believed to have been constructed during the 17th century, although precise details regarding its original builders and construction date remain unclear. Over time, the fort came under the control of various regional powers, including the Vijayanagara Empire, the Bijapur Sultanate, and later the Nawabs of Arcot, before being occupied by the British during the colonial period.
The structure features stone masonry walls, bastions, and entry gates, though much of the fort lies in ruins today. It offers panoramic views of the surrounding region and is a point of local historical interest. Limited archaeological or conservation studies have been documented in widely available sources.
Visitors can access the fort via a pathway leading to the hilltop. The site is maintained by the Tamil Nadu Archaeological Department, although preservation efforts appear to be minimal.
Accurate information regarding architectural specifics, historical events, and timeline of occupation is not fully confirmed due to scarcity of authoritative records.
