The jail, having three structures, was located on a 150-acre tea estate run by the Tamil Nadu Tea Plantation Corporation Limited (TANTEA) and remained unnoticed for long as it was hidden behind bushes and trees.
One out of the three structures was recently cleaned and all bushes were removed, after financial aid of Rs six lakh was granted under Hill Area Development Project, official sources said.
The prisoners were brought as slaves and made to work in the estate, they said, adding that disobedient prisoners were taken to the gallows, situated in a corner of the structure.
The area was used to cultivate Cinchona tree, the bark of which was used to make medicine for curing Malaria.
TANTEA has tied up with the tourism department to develop this as a tourist spot, as many things like plates, lanterns and other vessels, used at that time were also found at the estate.
Though the structures appear to be dilapidated from the outside, it could be developed as an international museum with necessary touch-up, the sources said.
