I grew up in a quintessential upper middle-class Chettiar family in Chennai. In the 1980s, most of my summer holidays were spent with my grandparents in Chettinad -- a region tucked deep down in South India between Trichy and Madurai. It is the residence of the Nattukottai Chettiars, a community of traders and bankers. After a long gap of 15 years, last summer I went back to revisit. Here's a compilation for fellow travellers seeking to unravel a new place and culture.
