Tucked away from the bustle of Chennai and the chic of Pondicherry, the East coast road leads to this quaint old town that has survived floods, a war, a tsunami, and a meagre audience. A UNESCO world heritage site, with over 400 listed monuments, Mahabalipuram- now known as Mamallapuram, boasts of marvels dating back to the 6th century! History buffs, get on a bike/auto/cab or just walk around this magnificence.
