Jambukeswaram.

There is said to have been a forest of Jambu trees near the Chandrateertha tank (filled with the water of the Kaveri) here and Shiva is said to have appeared under one of the trees as a Shiva Lingam. Legend has it that two devotees of Shiva were born under the influence of a curse as a white elephant and a spider. The elephant worshipped Shiva with flowers and water brought in its trunk (hence the name Tiru Aanaikka).

The spider worshipped the Lingam by spinning a web on top, to protect it from falling leaves. The elephants worship would destroy the spiders web, and the spiders web amounted to desecration in the eyes of the elephant leading to animosity between the two, of such proportion that a fight between them resulted in the death of both. The spider was born again in the royal Chola family (in Uraiyur - during the Sangam period). An interesting tale is associated with his birth. His parents Subhadeva and Kamalavati prayed to Nataraja of Chidambaram for a male successor.
The royal astrologer is said to have predicted an auspicious time for the birth of a successor who would be a ruler of great fame. The hour of birth approached sooner though and the royal queen bade her attendants to tie her legs and hang her upside down, with the aim of delaying the birth of the child. She achieved her objective although the royal offspring was born with reddened eyes, earning for himself the name 'Chenkannan' - the red eyed one. In his life time Ko Chenkannan is said to have been built several elevated temples - out of reach of elephants, keeping with the legend of his animosity with an elephant in his previous birth.

The stala vriksham is said to have grown out of a munivar, who offered his worship to Shiva.Akhilandeswari (Parvati) is said to have meditated upon Shiva here, and her shrine here, is considered to be of great significance. It is believed that Akhilandeswari was originally an Ugra Devata of great fury, and Adi Sankaracharyar is said to have converted the fiery energy of the deity into a manifestation of peace. Shrines to Vinayaka and Subramanya face Akhilandeswari. This temple has records of patronage from the Chola Pandya, Hoysala and the Madurai Naik kings. The temple is said to have been built by the Chola King Ko Chenkannan and it was of special significance to the Chola kings.
Ko Chenkannan is praised by tamil literature for having built more than seventy temples - and he is historically placed in the Sangam period (the very early years of the Christian era). Inscriptions from the tenth century AD testify to later Chola patronage. The Hoysalas who had a base near Samayapuram (near Tiruchi) built four temples in Northern Tiruvanaikkaval (Vallaleeswaram, Padmaleswaram, Narasimheswaram and Somaleswaram). The Pandyas and the Hoysalas contributed to the Eastern tower. Adi Sankara is said to have visited the Akhilandeswari shrine. He is said to have adorned her with ear-rings bearing the symbol of the chakram.
There is a shrine to Adi Sankara in this temple. This is a vast temple (18 acres) with lofty gopurams, 5 prakarams and ornate mandapams. The second and third prakarams date back to the 13th century. The dwajasthampa mandapam has grand sculptural work. There is an image of Ekapada Trimurthy representing the unity of Bhrama Vishnu and Shiva in this temple. The Akhilandeswari shrine is located in the fourth prakaram. The Eastern tower with seven levels has fine sculptural specimen of musical scenes, while the Western tower has nine levels. The first prakaram has been renovated in this century. Annual festivals here include the Pankuni Bhrammotsavam, Vasanta Utsavam, the float festival in Thai (Capricorn) , Aadi Pooram (Cancer) and the Pancha Prakara festival.
