The Anuradhapura Maha Viharaya was an important mahavihara or large Buddhist monastery for Theravada Buddhism in Sri Lanka. King Devanampiya Tissa of Anuradhapura founded it in his capital city of Anuradhapura. Monks such as Buddhaghosa and Dhammapala, who wrote commentaries on the Tipitaka and texts such as the Visuddhimagga, which are central to Theravada Buddhist doctrine, established Theravada Mahaviharan orthodoxy here. Monks living at the Mahavihara were referred to as Mahaviharavasins.
