Here Lord Vishnu became the disciple of Sri Ramanuja and received the name "Vaishnava Nambi"; Kaisika Ekadasi originated here.

According to the Sthala Puranam and ancient Sri Vaishnava Agamas, Divya Desam #97 (Thiruchirupuliyur / Thirukkurungudi) is revered as a sacred kshetram in Pandya Nadu. The presiding deity, Lord Azhagiya Nambi (Vaishnava Nambi), graces devotees in Ninra, Irundha & Kidandha (5 Nambis) posture facing East beneath the sacred Pancha Kethaka Vimanam, accompanied by Goddess Kurungudi Valli Nachiyar. Holy dips or prostrations near the Thiru Parkadal (Nambiyaru River) are believed to bestow peace, prosperity, and Moksha. Throughout the centuries, Chola, Pandya, Pallava, and Vijayanagara rulers contributed मंडपम्स (mandapams), gopurams, and stone inscriptions preserving the daily Pancharatra / Vaikhanasa Agama worship.
