The history of Srikurmam begins not with fortress walls or trade routes, but with a sacred site. This settlement emerged and developed around the unique Sri Kurmanathaswamy Temple—one of the world's rarest shrines dedicated to the tortoise avatar of the god Vishnu. Although the exact date of its founding is lost in the mists of time, ancient inscriptions on the columns testify that as early as the 11th–12th centuries, an active religious life flourished here, drawing pilgrims from various parts of India.
The city's heyday is closely linked to the era of the Eastern Ganga dynasty. The monarchs, and later representatives of the Gajapati dynasty, considered it their duty to patronize the temple, endowing the settlement with lands and privileges. Thanks to this political attention and its geographical proximity to the sea, Srikurmam became a meeting point of cultures: southern Dravidian traditions and the Kalinga style characteristic of neighboring Odisha were wonderfully intertwined in the architecture of local buildings.
A major milestone in the city's annals was the visit of the great philosopher Ramanujacharya in the 11th century, whose influence solidified Srikurmam's status as an important center of Vaishnavism. For centuries, the economy and way of life for local residents were built on the principle of a "temple town": skilled stonemasons, artisans, and clergy settled here, forming a special atmosphere that can still be felt in the ancient streets today.
