It is said that the King of Kalakkad visited the temple, seeking a cure for his leprosy. Upon completing his penance in front of the status of the serpent king, he was miraculously cured. In gratitude, the king ordered the repair and expansion of the temple, and made it into the current majestic structure that it is today. Chola king, the successor of Vijayalaya Chola (Tirugnanasambandar era) renovated many brick-built temples into stone ones and Thiruppampuram is one among them. Of the 15 inscriptions found in this temple, most are found in the outer ring –six in the north, one in east,four in west and two in the south. Of these, the oldest is from the period of Kulothunga chola the third (11 78-1218 AD).
