Sira

Sira (Kannada: ಶಿರಾ) is a town and taluk headquarters of Sira Taluk of Tumkur district in the state of Karnataka, India. It lies on the National Highway NH-4 (Mumbai - Chennai).
Sira Town was a strategically important place prior to the British Raj. It still has many historic structures. Among them are the Eidgah, Juma Masjid and the dargah or tomb over Mallik Rehan's grave. Mallik Rehan was the Governor of the dying Mughal Empire's south Indian domain under Emperor Aurangazeb. In the late 1600s Sira became a major province or 'Suba' of the Mughals.

Devarayana Durga

Devarayana Durga is a fortified hill, about nine miles east of Tumkur town, situated in the midst of picturesque 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 Bungalow 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.

Temple

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 addition 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.
