The second important hillock with an imposing citadel is known as Krishnagiri. It is also known as the English Mountain, perhaps because the British residents occupied the fort here, for some time. The Krishnagiri fort lies to the North of Tiruvannamalai road. It is smaller in size and height compared to the Rajagiri fort. A flight of steps of granite stones leads to its top. Another fort connected with Rajagiri with a low rocky ridge is called Chandrayan Durg, Chandragiri or St. George’s Mountain. The military and strategic value of this fort has been relatively less, but it has some interesting buildings of later period.

The third fort for some reason is called Chakkiliya Durg or Chamar Tikri - meaning the fort of the cobblers. It is not known why it had acquired such a name. Probably the royal saddlers and military shoemakers had set up their workshops here, as Gingee obviously was a military encampment. There is also 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. However, they provide challenging trekking opportunity to the visitors to Gingee.

Kapaleashwarar Temple is located in Mylapore, Chennai, Tamil Nadu. Nayanmars sing hymns in this temple. According to the Puranas, Shakthi worshipped Shiva, in the form of the Peacock, which is why the name Mylai was given to the area that developed around the temple, as 'Mayil' means Peacock in Tamil.The Pallavas kings built the temple around 7CE. The pallava Nayanamars built this temple.

The presiding God of this temple is a form of Shiva called Kapaleashwarar. The form of Shiva's wife Parvati at this temple is called Karpagambal (from the Tamil for "goddess of the wish-yielding tree"). Puranas have it that Lord Shiva was once telling Lord Brahma, the Hindu god of creation, about the creation of the three lokas but Lord Brahma did not agree with what Shiva said. Shiva got angry and plucked out one of Brahma's four heads. Brahma begged for forgiveness and was asked to perform penance at Mayilai (Mylapore) and then he asked Lord Shiva to take the name of Kapaleashwarar as Lord Shiva (eswarar) was wearing a necklace of skulls (kapala).

Any account of Gingee should include a description of the rock-cut shrine of Singavaram, situated about 3 kilometres (1.9 mi) from the fortress on a fifth hill called Singavaram hill. It is a unique Vishnu temple. The deity of the shrine is Lord Ranganatha. Lord Ranganatha is seen reclining on the serpent with his head turned to a side. The expression on the face of the Lord is benign and charming. The Gingee Ranganathan is ranked as one of the most beautiful Vishnu idols anywhere. It is interesting to note that the place where the Singavaram rock cut exists seems to have been originally a centre of Jain religion. Several small and large Jain rock cuts and monoliths are found around the temple. Gingee, hence, has emerged as an important surviving link of the Tamil Jain tradition. Singavaram hill is visited both by the Hindu and Jain pilgrims.

According to legend, it is the original image of Ranganatha from the famous Srirangam temple, which was taken away, from Srirangam and hidden in Gingee, for the sake of safety, during the plundering of Srirangam at the hands of the Mohammedan invader Malik Kafur. Lord Ranganatha is said to have been the tutelary Lord of Gingee and the personal deity (Ishta devata) of Raja Desingh. There is an underground tunnel that connects the Rajagiri fortress with the temple and is supposed to have been used by Raja Desingh and his queen to visit the temple unobserved. The existence of the tunnel itself is an indicator of the authenticity of the image. The fact that the idol was hidden among the rocks in a discarded Jain rock cut cave and was being worshipped unobserved by the public is enough proof of the idol being a very ancient and important one.

This tunnel is supposed to actually connect two towns, the great and little Gingee, surrounded by a wall. This wall is three 3 miles (4.8 km)in circumference and encloses the two towns and five mountains of rugged rocks on the summit of which were built five strong forts. The fifth mountain is Singavaram hill - in addition to the four already mentioned forts, namely, Rajagiri, Krishnagiri, Chandrayan Durg and Chakkili Durg. According to E. Scott Waring, Great Gingee referred to the whole area including Singavaram, and little Gingee was very likely to be Gingee proper, i.e., the area covered by four other mountains. There were two separate towns known as Sheo Gingee (Siva Gingee) and Vishnu Gingee (Vishnu Gingee - the latter being regarded by him as a popular and flourishing town) surrounded by walls of considerable circumference. The court of Sheo Gingee was formed into a citadel with basements and battlements and consequently thinly inhabited; Vishnu Gingee was flourishing and the resort of a large number of pilgrims, hence it can with great probability be identified with Singavaram. A visit to Gingee would be incomplete without a visit to Singavaram to see the reclining Vishnu and the Jain rock cuts.
