Dhammayangyi was built late in the reign of Sithu I (1113-1170), its magnificent pyramidal height dominating the surrounding plain. Like That-byin-nyu, the temple remained unfinished upon Sithu's death. Its cruciform floor plan, with shrines in each arm connected by a circumferential corridor, resembles the later Sulamani temple. Both temples have a solid central core, but in Dhammayangyi, the ambulatory and three of the four shrines were filled in with brick rubble, for reasons which even today remain mysterious.
