English: Sittanavasal Cave (also, Arivar Koil) is a 2nd-century Jain complex of caves in Sittanavasal village in Pudukottai district of Tamil Nadu, India. Its name is a distorted form of Sit-tan-na-va-yil, a Tamil word which means "the abode of great saints" (Tamil: சித்தன்னவாசல்).

The monument is a rock-cut monastery or temple. Created by Jains, it is called the Arivar Koil, and is a rock cut cave temple of the Arihants. It contains remnants of notable frescoes from the 7th century. The murals have been painted with vegetable and mineral dyes in black, green, yellow, orange, blue, and white. Paintings have been created by applying colours over a thin wet surface of lime plaster. Ancient caves such as Gol Gumbaz, Talagirishvara temple and this one are relatively unappreciated, while an argument like medieval period receive much attention does not stand true to itself
