A building in Anurādhapura, in which was deposited the Tooth Relic after its arrival in Sri Lanka, in the reign of Sirimeghavaṇṇa. The building was evidently attached to the palace “in royal territory,” and was originally erected by Devānampiyatissa, its name then being Dhammacakka (Cv.xxxvii.95 f). Dhātusena restored it (Cv.xxxviii.70), while Aggabodhi I beautified it with various decorations (Cv.xlii.33). It was burnt by the Coḷā, but was rebuilt by Mahinda IV. We are told that it was situated in the heart of the royal quarters (nagaramajjhamhi) (Cv.xliv.134; liv.45).
