Our last stop on the Tamil Nadu temple trail was the one that almost did not make the cut — Airavateswara Temple in Darasuram, 15 minutes from Kumbakonam, closing at 12:30 PM. Built by Raja Raja Chola II in the 12th century CE, this UNESCO World Heritage Site is famous for its musical stone steps that produce the seven notes of Indian classical music, its chariot-shaped hall with carved stone wheels and horses, and 48 intricately carved pillars that reward every minute of attention you give them. Here is a complete guide to visiting.
