The plantation is named in honor of H.V. Conolly, the then Collector of Malabar during the British rule who was instrumental in planting teak in the entire Nilambur area with the help of Shri Chanthu Menon,a forest officer under him. The plot extends across 2.31 hectares beside the Chaliyar river at Aruvakode, where the longest steel hanging bridge takes visitors across. This plantation was done about 150 years ago around the years 1842-1844 and was thus known as the world's first teak plantation. The plot has also been acclaimed for having the oldest living teak tree (girth 420 cms & height 46.5 meters) and Shri Chanthu Menon, was laid to rest in this very teak garden, Conolly's plot, as a mark of honour.
