Devarayana Durga
Geography
Devarayana Durga is a fortified hill, about nine miles east of Tumkur town, situated in the midst of picteresque scenery. It consists of three elevations and seven gates leading to the top. On the lowest elevation situated is the Lakshmi-Narasimha Swamy Temple. Near by is a spring know as Ane-done. On the slope of the hill is a pond said to the source of stream Mangali. Higher up is another small spring named Jaya-tirtha representing the source of another stream Jaya. Both the streams unite at Irukasandra at the foot of the hill and form the Jayamangali. The hills are also the source of the river Shimsha.
On the middle elevation are the Govt travellers Bunglow and few other places of rest. There are also two other springs known as Rama-tirtha and Dhanus-tirtha. There is a large cave nearby with figures of Rama, Sita and Lakshmana.
History
The place was originally known as Anebiddasari then as Jadakana Durga after a chief named Jadaka and finally as Devarayana Durga subsequent to its capture by Mysore king Chikka Devaraja Wodeyar.
Tradition relates that a robber chief named Andhaka or Lingaka had his stronghold here, and he was subdued by sumati, a prince, whose father, Hemachandra, was the king of Karnata and ruled from Yadupattana. On accomplishing the enterprise on which he had set forth, Sumathi is said to have established the city of Bhumandana near the present Nelamangala and taken up residence there for the protection of that part of his fathers kingdom.
Under the Hoysalas, there seems to have been, on the hill, a town called Anebiddasari or the precipice where the elephant fell. A rougue elephant, which the sthala purana describes as a Gandharva suddenly appeared before the town to the great consternation of the people and after doing considerable mischief, tried to walk up the steep rock on the west, when it slipped, fell back and was killed. The hill is accordingly called as Karigiri in the Puranas.
Under the Vijayanagara Kings, the use of the same name continued, and a large tank, named Bukkasamudra, was formed after throwing an embankment across the gorge from which the river Jayamangali has its source. Remains of the embankment and of the adjacent town can still be traced.
Lakshmi Narasimha Swamy Temple
The temple, built in the dravidian style of architecture, faces east and is said to have been constructed by Kanthirava Narasaraja I. From the inscriptions numbered Tumkur 41 and 42, we learn that the enclosure and tower were repaired in 1858 by the Mysore king Krishnaraja Wodeyar III.
A annual celebraton or jatra takes place in the month of Chaitra(March/April) at which thousands of people collect and many mantapas are built to accommodate them.
The TVS Group, a south indian automobile company, has helped a great deal in the improvement and maintenance of the temple environs.
Other Temples
On the third elevation stands, facing east, a temple of Narasimha, known as the Kumbhi. This Narasimha temple consists of a Garbhagriha, a sukanasi, a navagraha and a mukhamantapa and is similar to the plan of the temple below. In addittion to the temple there are three sacred ponds or Kalyani here known as Narasimha-teertha, Parasara-teertha and Pada-teertha.
There is also another temple, said to be older than Lakshmi Narasimha swamy, dedicated to Hanuman, also known as Sanjivaraya, who stands with folded hands.
Higher up above is a small shrine of Garuda.
Giri-Pradakshina
Legend has it that the devotees of Hindu temples used to perform the ritual of circling on-foot the hills on which temples were situated. As a effort to revive the practice, a large number of Devotees perform the Giri-pradakshina, organized by Vishwa Hindu Parishad(VHP)
