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