History

Aditya Chola constructed this temple during the 9th century. It is great marvel of Chola architecture, building technology and astronomy. The orientation is structured in such a way that it allows sunlight inside the temple, right on the sanctum only during the Tamil month of Chithirai (April/May). It bears another name called Surya Kottam or Keezha Kottam. The Karuvarai (Sanctum Sanctorum) of Nageswaran temple is similar to Sarangapani Temple, as it is made in the form of a Chariot. The temple consists of three gopurams in the eastern, western and southern directions. The temple is designed in such a way that during the first three days of Tamil month Chittirai (April - May), the rays of the Sun falls directly in the base of the presiding deity in sanctum sanctorum. The temple had been a centre of learning as seen from the inscriptions in the temple. The inscriptions indicate specific subjects like Purvamimansa styled as Pravahakarma. There were also provisions made for feeding and maintaining for teachers and students. In modern times, the temple is maintained and administered by the Hindu Religious and Charitable Endowments Department of the Government of Tamil Nadu. Architecture

The temple is one of the prominent Shiva temples in Kumbakonam. The temple shows early Chola art in its best form particularly in the form of human figures. The sanctum is of padabandha-padmaka type stands on padmopana. The lotus leaves of the padmopano are carved with vitality. In its iconographic scheme the Ardhanari, Brahma and Dakshinamoorthy in the niches of the outer wall are featured. The other sculptures on the walls almost life-size reflect either the donors to the temples or contemporary princesses and princes. The epic scenes are in low relief on the plinth below the pilasters of the walls of the sanctum, recalling the wood work. The Devi shrine is an independent structure situated in the outer prakaram(outer precincts of a temple), detached from the axial unit, though it faces south, a feature common to Saiva Devin shrines. The complex of Nataraja shrine is in the form of a chariot on wheel drawn by horses as in the case of Airavatesvara Temple at Darasuram and Sarangapani Temple in Kumbakonam. Similar architecture of halls (Mandapas) simulating a chariot drawn by elephant or horses is found in Sarangapani temple at Kumbakonam, Mela Kadambur Amirthakadeswarar Temple, Sikharagiriswara Temple, Kudumiyamalai, Vriddhagiriswarar Temple, Vriddhachalam and Thyagaraja Temple, Tiruvarur. According to historian Harle, the temple is counted among the four early extant temples of the Chola Empire, with the other three being Koranganatha Temple in Tiruchirappalli district, Moovar Koil in Pudukottai district, and Brahmapureeswarar temple in Thanjavur district. These temples follow the Pallava architecture which are relatively small in size. They all have a fair-sized porch, locally called ardhamandapa attached to the sanctum, both of which are slightly below the ground level in a pit kind of structure. The structures are also predominantly built of stone. During Rajendra Chola's Ganges expedition, the victorious chola army brought a beautiful Vinayagar statue as a war trophy to the chola empire. The Vinayagar statue was kept at this temple and was aptly named as Gangai Vinayagar. Currently, the Vinayagar is present in the ardha mandapam, in front of the sanctum of Nageswarar. The Vinayagar seems to be in the Pala style. Festivals and religious importance

The temple priests perform the puja (rituals) during festivals and on a daily basis. Like other Shiva temples of Tamil Nadu, the priests belong to the Shaiva community, a Brahmin sub-caste. The temple rituals are performed five times a day; Ushathkalam at 6:30 a.m., Kalasanthi at 8:00 a.m., Uchikalam at 12:00 a.m., Sayarakshai at 5:00 p.m., and Ardha Jamam at 8:00 p.m. Each ritual comprises four steps: abhisheka (sacred bath), alangaram (decoration), naivethanam (food offering) and deepa aradanai (waving of lamps) for both Nageswarar and Periyanayagi. The worship is held amidst music with nagaswaram (pipe instrument) and tavil (percussion instrument), religious instructions in the Vedas (sacred texts) read by priests and prostration by worshipers in front of the temple mast. There are weekly rituals like  (Monday) and  (Friday), fortnightly rituals like pradosham and monthly festivals like amavasai (new moon day), kiruthigai, pournami (full moon day) and sathurthi. Mahashivaratri during February - March is the major festivals celebrated in the temple. The major festival of the temple is the Brahmotsavam temple during Tamil month of Panguni when the Sun's rays fall directly on the image in the sanctum. Religious importance
Tirugnana Sambandar, a 7th-century Tamil Saivite poet, venerated Nageswarar in ten padigams in Tevaram, compiled as the First Tirumurai and second Tirumuari. Appar, a contemporary of Sambandar, also venerated Nageswarar in 12 padigams in Tevaram, compiled in the Fourth, fifth and sixth Tirumurai. Sundarar, the 8th century Nayanmar revered Nageswarar in seven padigams, which is compiled in Seventh Tirumuari. As the temple is revered in Tevaram, it is classified as Paadal Petra Sthalam, one of the 275 temples that find mention in the Saiva canon. The temple is counted as the 52nd in the list of temples in the northern banks of Cauvery. The temple is counted as one of the temples built on the banks of River Kaveri. The Sun rays falling on the image of Shiva is considered as the worship of Surya. As per a 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.
