According to the Puranas, the presiding deity of the place blesses the devotees with AninaVaram (Wanted Boon) the place is called Annavaram.
Sthala Puranam (Religious History) of Annavaram Temple…
The hillock by the side of the village is considered to be very sacred. Meru, the Lord of the hills, and his consort Menaka did great penance and begot two sons by the grace of Lord Vishnu. One was named Bhadra and the other Ratnakara.
Bhadra pleased Lord Vishnu with his devotion and penance and with his grace became Bhadrachalam on which Lord Sri Rama had permanently settled. Ratnakara desired to emulate his brother and succeeded in pleasing Lord Vishnu by his penance to settle on him as Veera Venkata Satyanarayana Swamy, Ratnakara remaining as Ratnagiri hill.
The temple of Sri Veera Venkata Satya-narayana Swamy is the main temple on the Ratnagiri hill. There is also a temple of Sri Rama and the shrines of Vanadurga and Kanaka Durga nearby. The temple of grama-devatha (village deity) is in the village at the foot of the hill.
It is said that Raja I.V. Rama-narayanam, the then zamindar of Gorsa and Kirlampudi estates, having been ordained by the Lord in his dream, traced the idol on the hill, worshipped it and installed it at the present spot on 2nd day of Shravana Masam, sravana suddha vidhiya, of the Telugu year Khara, 1891.
The Vishwakarma Brahmin stapathis architectural cognizance is at its best in sculpting this temple. The hillock itself is about 300 ft above sea level, green fields all-round the hills and the pampa river encircling Ratnagiri. About 460 well laid stone steps leads to the top of it.
The main temple constructed in the form of a chariot with the four wheels at each of the four corners. In front of the main temple is the kalyana mantapa, constructed and decorated with modern pieces of architecture. As we go down the way, we come across Ramalaya and then the shrines of Vana Durga and Kanaka Durga.
The Akriti of any temple is, according to the Agni Purana, merely a manifestation of the Prakriti. According to this the chariot of the temple is intended as a symbol of the Seven Lokas and the seven Lokhas above with, the garbhalaya of the Lord, at the heart’s center ruling over the entire Universe.
Significance of the Temple
The temple at Annavaram has been constructed to depict this idea concretely. The front side of the temple depicts the chariot. The Meru on the floor with the pillar at the center, and the idols at the top are intended to bring forth the idea that the Lord not only remains at the heart’s center but also permeates the entire universe.
The wheels depicting the Sun and the Moon serve to remind us that this Juggernaut moves on the wheels of time, and goes on for ever and ever, Thus the Annavaram temple satisfies both the ritualistic values and the spiritual aspirations of the devotees.”
