Srisailam, perched atop the Nallamala Hills on the banks of the Krishna River in Andhra Pradesh, holds the unique distinction of being revered as both one of the twelve Jyotirlingas (Lord Shiva as Mallikarjuna) and one of the eighteen Maha Shakti Peethas (Goddess Parvati as Bhramaramba Devi). This makes it an exceptionally sacred site for both Shaivas and Shaktas. Its origins trace back to antiquity, with references found in Puranas like the Skanda Purana and the Mahabharata. Archaeological evidence, including inscriptions, points to patronage as early as the Satavahana dynasty (1st-2nd centuries CE). The temple complex witnessed significant development and expansion under subsequent South Indian dynasties. The Ikshvakus, Chalukyas, Kakatiyas, and Reddi kings all contributed to its growth. However, the most extensive patronage came during the Vijayanagara Empire (14th-16th centuries). Vijayanagara kings, particularly Krishnadevaraya, considered Srisailam of great importance. They constructed massive prakarams (fort-like enclosure walls with bastions), grand gopurams (gateway towers), and elaborate mandapams (halls), transforming it into a vast temple-fortress complex showcasing Dravidian architectural styles. The temple also became a major center for the Virashaiva movement, particularly associated with the 12th-century saint Akka Mahadevi, who is said to have spent her final days in the caves near Srisailam. Adi Shankaracharya also visited Srisailam and composed his famous hymn Sivananda Lahari here. The complex houses separate shrines for Lord Mallikarjuna (represented by a natural Shivalinga) and Goddess Bhramaramba Devi, along with numerous other smaller shrines and mandapams. Despite periods of decline, particularly after the fall of Vijayanagara, Srisailam has remained a vital pilgrimage center, embodying the powerful confluence of Shaiva and Shakta traditions in South India.
