A mountain in the Malayarattha in Ceylon. Vijayabahu III. built on its summit a town which he made his capital. For a time the Tooth Relic and the Alms Bowl were there (Cv.lxxxi.15, 29) but were later removed to Billagiri (Cv.lxxxii.7ff). Parakkamabáhu II. also used Jambuddoni as his capital, but Vijayabáhu IV. moved the seat of government to Pulatthipura (Cv.lxxxx.13). Later, we find Bhuvanekabáhu I. being crowned in Jambuddoni, though his capital was in Subhagiri (Cv.xc.30). Vijayabáhu III. built the Vijayasundaráráma (q.v.) on Jambuddoni.
