It&rsquos as unexpected an address as any for a swish heritage property in a town rich with Gallic charms. Just opposite the home-cum-clinic of Dr B. Rajalakshmi Sakthivel, B.S.M.S., Siddha Physician, one door away from the diffident Soucilabai Government Girls Higher Secondary School, the mansion on Old Number 36, Vysial Street, stands honourably tall. There is no sweeping boulevard, promenade or beachfront to recommend WelcomHeritage&rsquos Calve but there is, instead, a rare streetscape of traditional continuous verandahs (thalavarams and thinnais), inviting even on hazy summer afternoons. The exquisitely restored 150-year-old edifice was once the residence of Telugu-speaking Chettiars who gave its street the French name of Rue Calve Subbraya Chetty. Yet, despite its proximity to nearly everything, this part of Pondicherry is, such a pity, easily missed.
