Tiruchchennampoondi is a small hamlet in Budalur taluk in Thanjavur district and about 30kms from Tiruchirappalli and 36kms from the district headquarters Thanjavur. Tiruchchennampoondi is one among the villages situated in the land stretch between the rivers Cauvery and Kollidam. The northern and southern banks of river Cauvery till it reaches the sea is flooded with ancient temples particularly of Chola period, in addition, also venerated by the Four Great Saiva Saints. Tiruchchennampoondi is also credited with an Early Chola temple dedicated to Lord Siva in the name Tirukadaimudi Mahadevar. The inscriptions mention the God as Thirukadaimudi Mahadevar, Thirukadaimudinathar and Tirusadaimudinathar and the village as Thirukadaimudi. However at present, the deity and temple is known as Sadaiyar and Sadaiyarkoil whereas the village as Thiruchinampundi or Thiruchannampoondi. The Goddess of the temple is Seethambika.
Kadaimudinathar temple is located on the north western side of the village. The temple has vimana, mukha mandapa and remnant of a maha mandapa, for which only the adhishthana is seen. The shrines of goddess Seethambiga and Chandeswara are on the northern side and both are brick structure. The temple lacks gopura or compound wall and lies in the open space. Being located in a remote area, aloof from the habitation, the temple was much dilapidated, collapsed and deserted. Recently, the Tamil Nadu State Archaeology Department renovated and now-a-days remain open for morning puja service. The grand old temple, a treasure trove of early architecture remains solitarily in the midst of a serene setup.

The God Thirukadaimudi Mahadevar and the village Thirukadaimudi are also mentioned in the inscriptions of nearby temples viz., Divyanageswaram temple and Appakudathan temple of Koviladi, the neighbourhood places of Tiruchchennampoondi. An inscription of Divyanageswaram temple refers Tiruchchenampundi, as Pandikulasani Valanattu, Vallanattu Melaimuri Tirukadaimudi Tirukadaimudiyudaya Mahadevar. As like, in the inscriptions of Thirupper nagar while speaking about the activities of Perunguri Mahasabaiyom referred the lands of Thirusadaimudi Thirusadaimudiyudaiya Mahadevar’. From these inscriptions the name of the place and the deity of this temple could be inferred. Koiladi is one of the Divyadesam and the inscriptions mention it as Thirupernagar.
