Adyar and the neighbouring Guindy had been used as hunting grounds by British officials of Fort St. George from the 1680s onwards though Adyar is first mentioned as a suburb of Madras only in a map from the year 1740 when the British purchased the village and integrated it with the Madras Presidency.[3]
