The Jetavanaramaya is a stupa, or Buddhist reliquary monument, located in the ruins of Jetavana monastery in the world heritage city of Anuradhapura, Sri Lanka. At 122 metres it was the world's tallest stupa and the third tallest structure in the world when it was built by King Mahasena of Anuradhapura. He initiated the construction of the stupa following the destruction of the Mahavihara. His son Maghavanna I completed the construction of the stupa. A part of a sash or belt tied by the Buddha is believed to be the relic that is enshrined here.
The structure is significant in the island's history as it represents the tensions within the Theravada and Mahayana sects of Buddhism; it is also significant in recorded history as one of the tallest structures in the ancient world; and the second tallest non-pyramidal buildings after Pharos of Alexandria; the height of the stupa was 400 feet, making it the tallest stupa in the ancient world.
