Tirunageswaram Naganathar Temple
Tirunageswaram Naganathar Temple also known as "Rahu Stalam" is a Hindu temple dedicated to the deity Shiva, located in Tirunageswaram, a village in the outskirts of Kumbakonam, a town in Tamil Nadu, India. It is significant to the Hindu sect of Saivism as one of the temples associated with the nine planet elements, the "Navagraha Stalas", and specifically Rahu. Shiva is worshiped as Naganathar, and is represented by the "lingam". His consort Parvati is depicted as Piraisoodi Amman. The presiding deity is revered in the 7th century Tamil Saiva canonical work, the "Tevaram", written by Tamil saint  poets known as the nayanars and classified as "Paadal Petra Sthalam". It houses four gateway towers known as "gopurams". The temple has numerous shrines, with those of Naganathar, Rahu and Piraisoodi Amman being the most prominent. The temple complex houses many halls; the most notable is the ornamental entrance hall built during the Nayak period. The temple has six daily rituals at various times from a.m. to 10 p.m., and twelve yearly festivals on its calendar. Legend. Thirunageswaram is one of the many temple towns in the state which is named after the grooves, clusters or forests dominated by a  particular variety of a tree or shrub and the same variety of tree or shrub sheltering the presiding deity. The region is believed to have been covered with Chamapaka forest and hence called Chamapakavanam. Many serpents, including Adishesha, Takshaka and Karkotaka, worshipped Shiva at this place, leading to the name "Tirunageswaram". As per Hindu legend, the king of snakes, Adisesha did penance at this place, called Senbaranya Kshetram on account of the presence of large number of Senbaga trees. Shiva was pleased by the penance and appeared to him. Since Shiva gave a boon to the king of Serpents, he  is called Naganathar. A Goddess Girigujambal is believed to be worshipping Shiva here with goddesses Lakshmi, Saraswathi, Ganesha, Muruga, and Shasta. Maha Bhairava is still believed to be guarding and assisting the divine mother during her prayers. The Goddess is said to be Swayambu as she is present in the form of Meru. Hence, no abhishekam (ablution) is performed for the image. As per a Hindu legend, Indra was cursed by sage Gautama as he misbehaved with the latter's wife Ahalya. To obtain deliverance from the sage's curse, it is said that Indra worshipped Giri-Gujambigai with a  scented material termed "Punugu" for 45 days. Sages like Gautama and Parashara and kings like Bhagiratha and Nala are said to have worshipped Naganathar at this place. The name "Kumbakonam", roughly translated in English as the "Jug's Corner", is believed to be an allusion to the mythical pot ("kumbha") of the Hindu god Brahma that contained the seed of all living beings on earth. The "kumbha" is believed to have been displaced by a "pralaya" (dissolution of the universe) and ultimately came to rest at the spot where the town of Kumbakonam now stands. The drops of nectar are  believed to have fallen onto five shrines around Kumbakonam, namely Mahlingeswarar temple at Tiruvidaimarudur, Tirudharasuram, Naganathar Temple at Tirunageswaram, Tiruvorgam and Tirupadalavanam. Architecture. The temple is located in Thirunageswaram, a panchayat town located from Kumbakonam and from Thanjavur on the Kumbakonam - Karaikkal highway. The temple is another masterpiece which exhibits the Chola style of architecture. It is believed to have been built by Aditya Chola I in the 10th century A.D. Later rulers have modified the temple with their own additions. The temple has a separate shrine for Rahu. The temple is located on the southern bank of the river  Kaveri 7 km from Kumbakonam. The temple campus encompasses exclusive shrines for Naganatha Swamy (Shiva), Pirayani Amman (Parvathi), Giri-Gujambigai (Parvathi) and Rahu with his divine spouses. Goddess Girigujambal has a separate shrine inside the temple campus as it is believed that the goddess is in "thava kolam" (mode of deep penance). The temple covers an area of South-North and East-West with concentric sub lanes and four major streets around the four sides. There are four gateways along the four sides with entry towers (gopuram) and a surrounding compound wall. In the broad pathway on the third precinct , there is a flower garden on the northern side. The Vinayaka shrine, Bali Peetam, Nandikeshwara hall and flag post are located in the eastern entrance. This Ganapathy shrine is said to have been installed by the great saint Sadasiva Brahmendra along with a Ganapathy yantra. An inscription in the temple bears testimony to this fact. The temple tank is called Sula Theertham, a dip in which, is believed to clear sins committed by human beings. The temple tank is located in the southern side and has a hundred pillared hall. The second precinct has a granite floor and enshrines the  Rahu shrine in the north eastern corner. The path leading to the main shrine in the second precinct has a hall decorated with Nayak style pillars with "yalis". The hall was constructed by Govinda Dikshitar, the minister of successive Nayak rulers, Achuthappa Nayak (1560–1614) and Raghunatha Nayak (1600–34). In the front hall on the eastern side, artistic pillar with "older and nine horses" design is found, while similar pillars are found on the southern side as well. There is a hall in the northern side with pillars decorated with "yalis" used for staging idols during the festive occasions. The renovation  work in the western walls was done during 1929 with artistic inscriptions. In the path way to main shrine, there are art works depicting Veda nayakas, king Sambumali and penance pose of Ambal. The Dwarapalaga images on each side at the entrance of Naganathar shrine are made of "chunam" clay. Worship and religious practises. The temple priests perform the "pooja" (rituals) during festivals and on a daily basis. Like other Shiva temples of Tamil Nadu, the priests belong to the Shaivaite community, a Brahmin sub-caste.

Rahu Peyarchi is a festival celebrated once every 1.5 years on the star when Rahu switches its planetary position from one "raasi" (galaxy) to the other. Religious significance. The ablution of the image of Rahu during Rahukaalam with milk turning to blue colour in this temple is considered to be a  miracle and attracts devotees from distant places. The presiding deity is believed to have been worshipped by many serpent deities like Adiseshan, Dakshan and Karkotaka. As per Hindu belief, people troubled by Sarpa-dosha or Malefic effects Rahu-Kethu seek a relief by offering prayers in a single day to Kudanthai or Kumbakonam Nageshwarar in the morning, Thirunageshwaram Naganathar at the noon, Thirupamburam Pambureswarar in the evening and Nagoor Nageshwarar or Naganathar temple at night. Tirugnana Sambandar, a 7th-century Tamil "Saivite" poet, venerated Naganathar in ten verses in "Tevaram", compiled as the "First Tirumurai". Appar, a contemporary of Sambandar , also venerated Annamalaiyar in 10 verses in "Tevaram", compiled as the "Fifth Tirumurai".
