- Thirukoshtiyur Sowmya Narayana Perumal Temple — This ancient Vishnu temple near Tirupathur is one of the 108 Divya Desams glorified in the Naalayira Divya Prabandham of the Alvars. It is famed as the place where the Vaishnava acharya Ramanuja proclaimed the sacred Ashtakshara mantra 'Om Namo Narayanaya' to all people from the temple tower, defying his teacher's instruction to keep it secret. Its landmark Ashtanga Vimana rises even taller than the five-tiered rajagopuram and enshrines the deity in three postures across its levels.
