Uttara Vihāra

Uttar-Vihara, also called Abhayagiri Vihara was a famous vihara in the ancient capital of Sri Lanka. This Vihara was one of the 4 Vihara built during the reign of King Tishya, which was also called the "Vihara of the North". One of the famous Atthakatha, Uttaravihara Atthakatha and Uttaravihara Mahavamsa were written here.

History
The credit for its Atthakatha writing is given to Thera Mahendra and other monks of Uttaravihara. Some information related to Indian history is also given in it.

It is mentioned in Buddhist literature that Mahendra stayed here.

According to Dr. Turner, the Mahavansha was based on Uttaravihara. According to Rhys Davids, the Atthakatha of Uttaravihara was one of the six early Buddhist Atthakathas.

While living in Uttaravihara, Mahendra had done the Pali translation of Maha-atthakatha, apart from this, he had expanded Uttaravihara Atthakatha and written it completely.
