India’s southernmost state of Tamil Nadu has long drawn in travelers and religious pilgrims who come to are drawn in by its elaborate Dravidian-style temples, some more than 1,000 years old. Other major attractions and things to do include Pondicherry, a former French colony that retains much of its colonial architecture to this day, and Auroville, a UNESCO-recognized global township first conceived in the 1960s. The cultural and political backbone of the state is Chennai, where you’ll find colorful temples, whitewashed old churches, and towering high rises competing for space in the skyline.
