This Ayyanar temple in Chettinad in Tamil Nadu is every year supplemented with mew clay horses, while the old ones decay with the monsoon rains and the winds. More than 1000 terracotta horses line the way to the temple. The horses are offerings to the Ayyanar. In South India, particularly Tamil Nadu, the Hindu village god Ayyanar is a popularly worshiped deity.
The temple can be visited while staying at Visalam, a CGH Earth Experience Hotel.
