Literally ‘copper building’. Name of the building serving as uposatha-hall (see uposatha.Skt., poṣadha) for the Mahāvihāra. Originally built by Devānampiya Tissa, it was pulled down and rebuilt by Duṭṭhagāmaṇi Abhaya as a nine-storey building roofed with copper plates, hence its name. The building underwent major repairs and reconstruction through the years and its name was changed to Maṇipāsāda, meaning ‘jewel building’, after Jeṭṭhatissa, who had offered to the building a very valuable jewel, had it rebuilt. As a result of the rivalry between the monks of the Abhayagiri and Mahāvihāra monasteries the building was destroyed, but was later rebuilt and subsequently underwent further renovations. Many famous sermons are said to have been preached in the Lohapāsāda.
