Located within the sacred city of Anuradhapura, the Abhayagiri Monastery (Abhayagiri Vihara) stands as one of the most significant monastic complexes in the history of world Buddhism. Established in the 1st century BCE, it was not merely a place of worship but a sprawling international university that challenged orthodox views and fostered a unique blend of spiritual and scientific advancement.
The Foundation and Rivalry
The monastery was founded by King Vattagamani Abhaya (better known as King Walagamba) in 89 BCE. The origin story is deeply rooted in local lore: as the King was fleeing from South Indian invaders, a Jain ascetic named Giri shouted, “The great black Sinhalese is fleeing!” After reclaiming his throne years later, the King demolished the Jain hermitage and built a Buddhist monastery, naming it “Abhayagiri”—a combination of his name (Abhaya) and the ascetic’s name (Giri).
For centuries, Abhayagiri was the primary rival to the Mahavihara (the Great Monastery). While Mahavihara was the bastion of orthodox Theravada Buddhism, Abhayagiri was known for its progressive, cosmopolitan outlook. It embraced Mahayana and Vajrayana influences and welcomed scholars from across Asia, making it a melting pot of Buddhist philosophy.
Architectural Marvels: The Great Stupa
The centerpiece of the complex is the Abhayagiri Dagaba. At the time of its completion, it was one of the largest structures in the ancient world, second only to the pyramids of Giza in height among non-monumental buildings. Built over a footprint of the Buddha, the stupa reached a height of approximately 115 meters (377 feet).
The monastery also features the world-renowned Kuttam Pokuna (Twin Ponds), which showcase the pinnacle of ancient Sinhalese hydraulic engineering and landscape architecture. The sophisticated filtration and water inlet systems used for these ponds are still studied by engineers today.
A Center for International Learning
By the 5th century CE, Abhayagiri had grown into a massive institution housing over 5,000 monks. Its fame reached far beyond the shores of Sri Lanka. The famous Chinese monk-traveler Fa-Hien spent two years at Abhayagiri, documenting its grandeur and the meticulous rituals surrounding the Sacred Tooth Relic, which was housed at Abhayagiri during that era.
The monastery was also a pioneer in the arts. The Samadhi Buddha Statue, located within its grounds, is considered the finest example of Sinhalese sculpture, depicting the Buddha in a state of deep meditation with a serenity that has captivated visitors for over a millennium.
The Legacy of Abhayagiri
Although the monastery fell into ruin following the Chola invasions and the eventual shift of the capital to Polonnaruwa, its influence remains. Today, it is a UNESCO World Heritage site. Recent restorations have brought the Great Stupa back to its former glory, standing as a testament to an era when Sri Lanka was a global beacon of intellectual and spiritual light.
