The Alangudi Guru Temple has a rich history dating back to the Chola dynasty. Inscriptions within the temple complex indicate contributions from various rulers over the centuries. Legend has it that Lord Shiva appeared before Sage Agastya under a Vilva tree, hence the name Alangudi (grove of banyan trees). The temple's main deity, Apatsahayesvarar, is believed to protect devotees from adversities and grant them relief from sufferings. Over time, the temple has undergone several renovations and expansions, with significant contributions from the Pandya and Vijayanagara empires. Today, it stands as a testament to the enduring faith and architectural prowess of ancient South Indian dynasties.
