A tank in Anurādhapura, north of the royal palace, in the time of Devānampiyatissa.
When Mahinda scattered flowers on it the earth trembled, and Mahinda prophesied that it would become the Jantāghara-pokkhoranī situated to the east of the gateway of the Kālapāsāna-parivena.
It had disappeared by the time the Mahāvamsa Tīkā was written (MT.344f).
The sīmā of the Mahāvihāra passed through the tank. Mbv.135, 136.
