There was a place of this name to the east of the Lohapāsāda in Anurādhapura. Once when the Dīghabhāṇaka Theras recited the Brahmajāla Sutta there, the earth trembled from the water upwards (DA.i.131).

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-palace of the goddess Bīranī. The central part of the palace was called the Ambalaṭṭhikapāsāda. “It was visible from every side, bright, with pennons hung out.”

Duṭṭhagāmaṇī probably included a similar central part in the Lohapāsāda. This view is strengthened by No.4 below.
