Is Ruwanweli Seya a feast of civil engineering marvel, enshrining the relics of Lord Buddha or did it have a higher purpose? Designed by Arhants or enlightened ones themselves archaeologists and investigators inquire the greater purpose of a stupa whose construction was predicted by Buddha and was awaited by Arhants, gods and humans. Built nearly 2500 years ago,accomplishing a prediction made by Lord Buddha himself, Ruwanweli Seya or the pagoda of golden dust, was one of the largest structures in the ancient world, standing 103 m tall with a circumference of 290 m. Also known as the Mahathupa, Swarnamali Chaitya, Suvarnamali Mahaceti and Rathnamali Dagaba, the stupa is an engineering feast and a testimony to the engineering capabilities of the ancient Sri Lankans.
