1. Ambalaṭṭhikā.– A royal park on the road between Rājagaha and Nāḷandā. It contained a royal rest-
It was one of the spots in which the Buddha rested during his last tour, and we are told that while there he discoursed to a large number of monks (D.ii.81; he remained there one night, UdA.408). However, the most famous of the Buddha’s discourses in Ambalaṭṭhikā seems to have been the Rāhulovāda Sutta named Ambalaṭṭhika-
However, see below (4) for a more probable explanation.
2. Ambalaṭṭhikā.– A park in the brahmin village Khāṇumata. The Buddha went there during one of his tours through Magadha. On this occasion he taught the Kūṭadanta Sutta (D.i.127). Buddhaghosa (DA.i.294) says the park was like the pleasance of the same name between Rājagaha and Nāḷandā.

On another occasion King Vasabha heard the Dīghabhāṇakas reciting the Mahāsudassana Sutta, and thinking that they were discussing what they had eaten and drunk, he approached closer to listen; when he discovered the truth he applauded the monks (DA.ii.635).
The place referred to here was probably not a park, but a building that formed part of the Lohapāsāda. In the Mahāvaṃsa account (Mhv.xxvii.11‑20) of the building of the Lohapāsāda we are told that the plans were copied from the gem-
Duṭṭhagāmaṇī probably included a similar central part in the Lohapāsāda. This view is strengthened by No.4 below.
4. Ambalaṭṭhikā.– According to Buddhaghosa (MA.ii.635), the Ambalaṭṭhikā, in which the Rāhulovāda Sutta of that name was taught, was not a pleasance, but a pāsāda, a kind of meditation hall (padhānagharasaṅkhepa) built in the outskirts of Veḷuvana-
