The Gingee Fort complex is on three hillocks: Krishnagiri to the north, Rajagiri to the west and Chandrayandurg to the southeast. The three hills together constitute a fort complex, yet each hill contains a separate and self-contained citadel. Connecting them – forming an enormous triangle, a mile from north to south, punctuated by bastions and gateways giving access to the protected zones at the heart of the complex. The fort walls are and the three hills are connected by walls enclosing an area of . On the top of the hillock, there are minor fortifications. Ranganathar Temple, bell tower, watch tower, cannon and draw bridge are located atop the hill.

Krishnagiri The second important hill with an impressive citadel is called
Krishnagiri fort, also known as the
English Mountain, perhaps because of the British residents who occupied the fort here for some time. While the greater complex is potentially significantly older, File:Kistnagherry_Krishnagiri.jpg| File:Kistnaghurry.jpg| File:East View Of Kistnaghurry.jpg| File:Fort of Krishnaghirry.jpg|Fort of Krishnaghirry
Chakkiliya Durg The third fort for some reason is called Chakkiliya Durg or Chamar Tikri – meaning the fort of the Chamars. It is not known why it had acquired the name. Probably the royal
Chamar warriors used to stay here, as Gingee obviously was a military encampment. There is a smaller and less important fourth hill, the summit of which is also well fortified. There is nothing much left of Chandrayan Durg and Chakkilli Durg. Their flanks are now completely covered with thorny shrubs and stone pieces. ==Culture==
