Established in the 2nd century BC in Anuradhapura, Abhayagiriya Vihara is one of the world’s most significant ancient monastic ruins. It was both a sacred sanctuary and a legendary international university hosting thousands of scholars. Its centerpiece is a colossal brick stupa that once rivaled the heights of the Egyptian pyramids. Surrounded by lush greenery, intricate stone carvings, and the serene Samadhi Buddha statue, this UNESCO World Heritage site offers travelers a deeply spiritual look into Sri Lanka’s golden age.
