Built in Chola architectural style and attributed to the Chola dynasty, the temple gives the village of Kuruvalapparkovil its name. It is a notable Vaishnavite pilgrimage stop in the northern part of the district.

A historic palayam (zamindari) town, once the seat of the Udayarpalayam Palayakarars whose fort and estate made it a regional power centre. Today it is a taluk headquarters in northern Ariyalur district; the old palace survives as its landmark.

An early Chola Shiva temple at Periyathirukkonam, listed among the district's historically important temples of the Chola period, with its deity worshipped as Adimadyarjunar (Adhimoolanathar).

A historic Catholic pilgrimage shrine linked to the Italian Jesuit missionary and Tamil scholar Constanzo Beschi (Veeramamunivar), who served here in the 18th century. Its annual feast draws pilgrims from across Tamil Nadu.

The great Shiva temple built c. 1035 by Rajendra Chola I as the centrepiece of his new imperial capital, celebrating his conquest of the Gangetic plains. It is a UNESCO World Heritage Site as one of the Great Living Chola Temples.

An excavated mound about 3 km from the Gangaikonda Cholapuram temple where the Tamil Nadu State Department of Archaeology unearthed the remains of the imperial Chola royal palace, built in burnt brick with flat-tiled roofing. It served as the administrative seat from which Rajendra I and later kings such as Virarajendra and Kulottunga I issued royal edicts, corroborated by inscriptions dated between 1031 and 1119 CE. Excavations from 1980 onward recovered iron nails, ivory objects, Chinese ceramics, coloured bangles, gold foil and copper coins.

A Chola Shiva temple at Sennivanam whose inscriptions place it in the reign of Rajendra Chola I (1012-1044 CE), with the presiding deity worshipped as Thirthapurishwarar. It forms part of the cluster of dated Chola shrines in the district alongside the temples at Sendurai and Sripurandan.

A Vishnu temple at Kallankurichi where the presiding deity Kaliyuga Varadaraja Perumal, popularly called Kaliyaperumal, is worshipped. Local tradition holds that the temple was built roughly five centuries ago by a cowherd at the spot of a post believed to hold miraculous powers, though the deity itself is considered far more ancient. It is one of the better-known Vaishnavite shrines of the district and lends its name to the limestone-rich locality around it.

The Kallankurichi limestone belt is where a fossilised dinosaur egg was unearthed in 1992 in the cement-factory mines and later certified by experts, with further clusters of titanosaur eggs identified nearby. The site lends its name to the Kallakurichi Formation, a Maastrichtian (Late Cretaceous) marine unit of the Ariyalur Group rich in ammonites, corals and molluscs. It is one of the district's most significant palaeontology and geology sites for students and researchers.
