Most Sri Lankans know the Minneriya Wewa Reservoir, the vast reservoir whose waters sustain a thriving agricultural community—and its builder, King Mahasen (276-303 CE), who came to be revered as Minneri Deviyo. Yet few have truly experienced the serene sanctuary of Nagalakanda, nestled at the foot of that very tank. Here, the teachings of Dhamma have been whispered on the cool breezes for centuries.

Although the exact date of Nagalakanda’s founding and the identity of its builders remain shrouded in mystery, the scattered ruins speak of a once vast Buddhist monastic complex. Archaeologists, intrigued by its religious structures and ruined Buddha statues, often attribute the site to the Middle Anuradhapura period.

In 2003, under the UNESCO Sri Lanka Cultural Triangle Project’s Alahana Pirivena survey, researchers conducted a systematic surface exploration of Nagalakanda. Their report revealed not only the wealth of monuments still standing but also numerous relics already damaged or destroyed. Today, travelers journeying from Habarana toward Polonnaruwa can glimpse these ancient stones against the backdrop of lush paddy fields nourished by the Minneriya Wewa Reservoir. It is easy to imagine a larger, more prosperous community once dwelling here—one guided by Buddhist teachings toward both material abundance and spiritual cultivation.

Threats to Heritage and Ongoing Conservation

The stupa’s relic chamber and its four directional walls have been repeatedly excavated and left in ruins. A timely conservation effort is urgently needed before the remaining brick walls collapse entirely. It is equally regrettable that the once-expansive sacred grounds now cling to a fraction of their original extent. Even the ancient Balumgala—a viewing rock said to have served as a royal lookout—has been overshadowed by telecommunications towers erected under dubious claims of “ancient rights.” Political land grabs and the sounds of live‑fire exercises from nearby military ranges further disrupt the peace essential for meditation and reflection.

In the face of such obstacles, it falls to us to rekindle Nagalakanda’s past glory and preserve its Buddhist heritage. May this rocky peak, rising from the calm waters of the Minneriya Tank, once again become a place where virtue is nurtured and the fragrance of Dhamma fills the air.
