Justices K K Sasidharan and G R Swaminathan of the Madurai Bench gave the direction during the hearing of a PIL filed by Kanzimozhi, an advocate, and said the excavation site should remain open.
The petitioner had sought to continue with the excavation and also set up a museum at the site.
The judges pointed out that it will be proper and best for the site to remain open. Even Harappa and Mohenjodaro excavation sites remained open till now, they said.
The petitioner said that excavation site was the first Tamil civilisation along a river bed. About 3,500 artefacts had been collected from the site which prove that the Sangam age (200 BC) was not fiction, but real.
The articles depicted the ancient Tamil civilisation, heritage and they should be displayed in a site museum, the petitioner said.
