Kallankurichi

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. This temple guide belongs to the Kallankurichi planning base in Ariyalur, Tamil Nadu, with route context, best-time notes and verified inventory categories for stays, food, operators, shops, wellness and transport as they are approved.

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.
