A mountain, slightly over two yojanas to
the south-east of Anurādhapura. At the foot was a bamboo-grove in which grew
three bamboo-stems, each being a waggon-pole in girth - known as latāyatthi,
kusumayatthi and sakunayatthi - because of Devānampiyatissa's good fortune
(Mhv.Xi.10; Dpv. xi.15, 19; Sp.i.74. For an explanation of these yatthis see
IHQ.vi.571ff). Saddhātissa afterwards built a vihāra there, called the
Chātavihāra (MT.300). The Anguttara Commentary (i.15) has a reference to a
novice dwelling in Chātapabbata who came to grief after hearing a woman's voice.
