A 400ft archaeological marvel conceptualised by King Mahasen, Jethawanaramaya is truly magnificent. It sits in the midst of the ruins of a great monastery and is the largest stupa in Sri Lanka. It is believed that the stupa was built where Mahinda Maha Thero was cremated. Being one of the most significant stupas located in Anuradhapura, the dome brickwork is awed for its workmanship and engineering ingenuity. The stupa is constructed as a series of 93,300,300 burnt brick layers.
