The Anuradhapura Maha Viharaya was an important mahavihara or large Buddhist monastery for Theravada Buddhism in Sri Lanka. King Devanampiya Tissa of Anuradhapura (247–207 BCE) founded it in his capital city of Anuradhapura. Monks such as Buddhaghosa (4th to 5th century CE) and Dhammapala, who wrote commentaries on the Tipitaka and texts such as the Visuddhimagga, which are central to Theravada Buddhist doctrine, established Theravada Mahāvihāra of the Tambapaṇṇiya (Pali; Sanskrit: Tāmraparṇīya or Tāmraśāṭīya) orthodoxy here. The monks residing at the Mahāvihāra came to be known as the Mahāvihāravāsins.
In the 5th century, the Mahāvihāra was likely the most advanced center of learning in southern or eastern Asia. It attracted numerous international scholars, who studied a wide range of disciplines under a highly structured system of instruction.
