Somaya a Buddha Pikkuni from Poompuhar donated one of the beautifully sculptured pillars that were erected by the Sunga-Kings of North-India during the second century B.C. The pillars carry the inscription Kaganthia Somaya Pikkunia Thanam which means “This Pillar was donated by Somaya Pikkuni of Poompuhar.” Buddhism flourished in Poompuhar two thousands years ago.
