Annavaram is accessible through regular bus services provided by the Andhra Pradesh State Road Transport Corporation (APSRTC), with buses operating every 30 minutes from Kakinada and Rajahmundry.

[6] The temple's origins are linked to a vision experienced by a devout Brahmin named Eeranki Prakasa Rao (ఈరంకి ప్రకాశరావు), who lived in the village of Annavaram, located near Pithapuram.

During the period of Raja Inuganti Venkata Ramarayanim Bahadur (రాజా ఇనుగంటి వేంకటరామరాయణిం బహదూర్), both Prakasa Rao and the local ruler had a simultaneous dream in which Lord Vishnu instructed them, "On the forthcoming Sravana Sukla Vidiya, under the Makha Nakshatra on a Thursday, I will manifest on the Ratnagiri Hill.

"[4] Following this divine revelation, Prakasa Rao and the ruler shared their visions with the villagers and prepared to visit Annavaram on Sravana Sukla Padyami of the Khara year.

[4] On August 6, 1891 (Salivahana Saka 1813), the idol was consecrated following the traditional Vishnu Panchayatana system, alongside the installation of the Sri Matripada Vibhuti Maha Vaikuntha Narayana Yantra, which had been brought from Kasi.

Similarly, Ratnakara's penance was rewarded when Vishnu appeared as Sri Veera Venkata Satyanarayana Swamy on the Ratnagiri Hill, also known as Ratnachalam.

Architecturally, the temple is designed to resemble a chariot, complete with four wheels at each corner, symbolizing the Jagannath concept of eternal movement through time.

[4] The main sanctum houses an idol that is approximately 13 feet tall and cylindrical in shape, symbolizing the unity of the Trimurti with Brahma at the base, Siva in the center, and Vishnu at the top.

The first floor holds the principal deity, Sri Veera Venkata Satyanarayana Swamy, accompanied by Goddess Anantha Lakshmi and Lord Siva.

[8] The temple attracts thousands of devotees daily, who visit to perform the Satyanarayana Vratham for various reasons, including wealth, health, and prosperity.
