Karaikudi and the 73 surrounding villages contain some of the most extraordinary domestic architecture in India — the palatial mansions of the Nattukotai Chettiar community, built in the 19th and early 20th centuries from the profits of trading networks stretching across Burma, Malaysia, and Ceylon.
The houses follow a strict plan: a series of connected courtyards, from the formal reception rooms at the front to the women's quarters and kitchen at the back, each court open to the sky. The materials are startling — Burmese teak pillars, Italian marble floors, Belgian glasswork, Chinese ceramic jars arranged in rows in the corridors. Many houses stand empty now, their owners in Chennai or Singapore, the marble dusty and the teak drying in the heat. Some have been converted into heritage hotels; others can be visited by arrangement with the families or through local guides. Walking the streets of Karaikudi and the village of Kanadukathan (12 km north) is the best way to understand the scale of what was built here.
