The history of the Annavaram temple is steeped in legend and tradition. It is believed that the deity, Lord Satyanarayana, manifested himself here after a local zamindar had a divine dream. The temple was subsequently built on the Ratnagiri Hills. The original structure was modest, but over time, it has expanded into a grand complex. The temple has been patronized by various rulers and devotees over centuries. The Satyanarayana Vratham gained popularity through this temple, becoming a widely practiced ritual. The temple's growth and popularity are a testament to its spiritual significance and the devotion of its followers. It continues to be a major center of pilgrimage and religious activity in Andhra Pradesh.
