Sabbannu Phaya, which is also known as Thatbyinnyu Phaya (fig.), is the tallest Buddhist temple in Bagan. Though essentially in the jaturamuk style, i.e. with four entrances, the eastern portico projects further than the other porticoes, breaking the symmetry.

The eastern portico has a central stairway, flanked by two standing sentinels, that leads to an intermediate storey where an ambulatory forms a continuous passage way around the centre of the building, while two levels of windows provide the interior of light and a breeze of air.
