Ruwanwelisaya, situated in the ancient city of Anuradhapura, Sri Lanka, is a monumental stupa of profound religious and historical significance. Constructed over 2,000 years ago by King Dutugemunu, this architectural marvel rises to a height of over 100 meters and boasts a diameter of approximately 91 meters at its base. Commissioned as an expression of gratitude following the king’s triumph over the South Indian invader, King Elara, Ruwanwelisaya serves as a repository for one of the eight sacred relics of the Buddha. The stupa, with its classic Sinhalese design, features a hemispherical dome enclosing the relic chamber, and its sheer scale and symmetry are awe-inspiring. The surrounding Mahamevna Uyana complex, adorned with ancient ruins and serene ponds, adds to the spiritual ambiance. Pilgrims and visitors flock to this site to engage in religious rituals, paying homage to the Buddha and marveling at the historical and cultural legacy embodied by Ruwanwelisaya. Despite undergoing restorations over the centuries, the stupa stands as a resilient symbol of Buddhist devotion and Sri Lanka’s enduring heritage.
