Dhammayazika Phaya is brick structure with a bells-shaped, golden zedi and was built in 1198 AD, by King Narapatisithu, in order to house four holy relics that the latter received from the King of Sri Lanka.

It has a pentagonal layout with three receding terraces, that contain a number of gilded stupas, several greyish sandstone chintha, as well as some outward facing and seated thevada-like guardian figures in red-orange-brown rust colour, whilst the walls of the highest terrace was originally ornamented with terracotta tiles depicting scenes from the jataka, though many of those have over time gone missing.
