Padmanabhaswamy Temple and Palace

Vilvamangalathu Swamiyar, residing near Ananthapuram Temple, Kasargod prayed to Lord Vishnu for his darshan. The Lord came in disguise as a small, mischievous boy. The boy defiled the Saligrama which was kept for Puja. The Sage became enraged at this and chased the boy. The boy disappeared. The Sage reached Ananthankadu searching for the boy. There he saw the boy merging into an Iluppa tree (Indian Butter Tree). The tree fell down and became Anantha Sayana Moorti (Vishnu reclining on Anantha). But the Lord was of an extraordinarily large size with head at Thiruvallom, navel at Thiruvanananthapuram and lotus-feet at Thrippadapuram (Thrippappur). The Sage requested the Lord to shrink to a smaller proportion – thrice the length of his staff. Immediately, the Lord shrank. But even then many Iluppa trees obstructed a complete vision of the Lord. The Sage saw the Lord in three parts – thirumukham, thiruvudal and thrippadam. The spot where the Sage had darsan of the Lord belonged to Koopakkara Potti and Karuva Potti. With the assistance of the reigning King and some Brahmin households a Temple was constructed. Koopakkara Potti was made the Tantri of the Temple.

Ananthankadu Nagaraja Temple still exists to the north west of Sri Padmanabhaswamy Temple. The Samadhi (final resting place) of the Swamiyar exists to the west of the Sri Padmanabha Temple. A Krishna Temple was built over the Samadhi. This Temple, known as Vilvamangalam Sri Krishna Swami Temple, belongs to Thrissur Naduvil Madhom.
