A locality near Ambatthala. While seated here,
Devānampiyatissa heard the novice Sumatra announce the time for the preaching of
the Dhamma, to be heard all over Ceylon (Mhv.Xiv.36). Geiger (Mhv. Trs. 94, n.1)
identifies it with the modern Nāgapokupa (but see Nāgasondi).
According to the Dpv.vamsa (Dpv.xiv. 58; also Mhv.xvi.6)
(which has a v.l. Nagaracatukka) it was a pond at the foot of the Missakapabbata
and was made out of rock.
