Chettinadu is a region in the Sivaganga district of Tamil Nadu. It is the home of the Nattukottai Chettiars, a prosperous banking and business community. The region is well known for its charming 19th-century mansions. Athangudi tiles in myriad colours and patterns are made here by a unique process using local soil and glass plates. Spicy, aromatic Chettinadu cuisine is another speciality of this region. The cotton saris woven here are dramatic and multi-hued with vibrant, bold checks, stripes and contrasting rainbow colors and borders.
