Rajagiri Fort

Rajagiri Fort is the largest and highest hill fort of the Gingee Fort complex located in Gingee town, Villupuram district, Tamil Nadu. Perched at about 800 feet elevation, it forms part of the fortified triangle with Krishnagiri and Chandrayandurg hills. Noted for its strong granite walls, citadel, granaries, temples and Kalyana Mahal, it is maintained by the Archaeological Survey of India and is regarded as one of Tamil Nadu's most impressive hill forts.

Visitors can expect a steep climb of stone steps to the hilltop citadel with massive granite ramparts, bastions, granaries, prison cells, temples and ruined palaces. The fort offers panoramic views of the surrounding plains and the other two Gingee hills. The lower enclosure contains the Kalyana Mahal, gymnasium and water tanks. The terrain is rocky and exposed with limited shade, requiring moderate trekking effort to explore the upper fort.

Rajagiri Fort is part of the Gingee Fort complex whose origins are traced to the Chola period around the 9th century and later developed by the Vijayanagara Nayaks in the 13th-16th centuries. It was subsequently held by the Marathas, Mughals, French and British. The fort was strengthened with granite walls, granaries and military structures and was considered highly defensible due to its hilltop location and fortifications.

The fort complex includes temples, mandapas and palace structures such as Kalyana Mahal reflecting Vijayanagara architectural style. It is an important heritage and archaeological site in Tamil Nadu and forms part of the cultural landscape of the Gingee region, attracting visitors interested in history, architecture and traditional fort design.
