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.
