The Agastyesvara temple at Anangur is also called Tirukkarrali Mahadevar (the stone temple of Mahadevar). Sembiyan Mahadevi built this stone temple during the reign of Uttama Chola (971 - 988 CE). The temple bears inscriptions recording information on patronage and donation of gifts in the reign of Uttama Chola, Rajaraja I (985-1014 CE) and Vikrama Chola (1118-1135 CE). References: S.R.
