A town in Kosala, near the Himālaya. It has been given, free from all taxes (as brahmadeyya), to Pokkharasāti by the king of Kosala, in recognition of the former’s skill. It was thickly populated and had much grassland, woodland and corn. DN.i.87 The Icchānaṅgala wood was in the neighbourhood, and when the Buddha was staying in the wood Pokkharasāti first sent his pupil Ambaṭṭha and then went himself to visit the Buddha.
There was a road which connected Ukkaṭṭha with Setavyā. AN.ii.37
It was in the Subhagavana at Ukkaṭṭha that the Mūlapariyāya Sutta MN.i.1ff. was preached.
In the Brahmanimantika Sutta MN.i.326 SN.i.142 the Buddha says that it was while he was residing at Subhagavana that be became aware of the erroneous views of Baka-brahma and went to the Brahma-world to teach Baka the truth.
