After seeing Thirumayam fort we went to Kanadukathan (கானாடுகாத்தான்) to see Chettinad palace, the palatial house of Sri MAM Ramaswamy and family. Chettiyars hail from Chettinad region are a prosperous banking and business community who traveled across South East Asia doing trade especially during Cholas and later the British empire. To go inside the Chettinad Palace you need to get prior permission from the family which we were lucky to get through a friend in Tanjore.
After Kanadukathan we went to Athangudi to see the Big House (ஆத்தன்குடி பெரிய வீடு), this too is a palatial house slightly on a smaller scale compared to Chettinad Palace but matching in the grandeur of interiors. Tourist are welcome inside to see the house after buying a ticket for Rs.50 (~USD 1).
