A rock painting of the Iron Age period was found in a hillock near Krishnagiri. This is one of the 11 rare rock paintings found in the hillocks of the district and within a radius of six kilometres from the town.
According to Sugavana Murugan, a government school teacher and also a freelance archaeologist, only three of the paintings have been studied and the rest are yet to be documented.
The first rock painting was found near the Gothigundu rock in 1972 by late Ramanujam, a Tamil Pandit who worked in the Government Boys Higher Secondary School. Megalithic potteries were also found in large numbers in and around Pethalapalli hillocks.
The need of the hour is to survey rare ancient rock paintings in the three hillocks around Krishnagiri and safeguard them, said Mr. Sugavana Murugan.
