The Htilominlo Temple is situated in Nyaung U and Wetkyi-In Region of Bagan. The temple is about 1.5 km northeast of Bagan. This large temple was built by King Nantaungmya in 1218. The temple is known to be the last Myanmar Style temple built in Bagan. The name is a misreading of the Pali word for ‘Blessings of the Three Worlds’.
King Nantaungmya erected the temple on this spot because it was here that he was chosen, from among five brothers, to be the crown prince. Nantaungmya was King Narapati Sithu’s son. The selection of the heir to the throne had a tradition, which was to erect a white umbrella and the future ruler would be chosen when the white umbrella tilts in his position. After the event, it was decided by the state policy’s council. Inside the 46-metre-high temple, which is similar in design to Sulamani Temple, there are four Buddhas on the lower and upper floors. Traces of old murals are also still visible. Fragments of the original fine plaster carvings and glazed sandstone decorations have survived on the outside. The doorways feature nice carved reliefs. Several old horoscopes, painted to protect the building from damage can be found on the walls of the temple.
There were also many ordination halls, called thein in Myanmar, from the Pali, Sima. They were used not only for the ordination ceremony itself, but also for other such ceremonies as the confession by monks. The Upali Thein has a long central nave with a ridge roof and a pair of side aisles with lean-to roofs. Inside, there is an image of the Buddha placed on a pedestal near the western end.
