This is maybe the only Hindu temple present in Bagan. There are several statues of Vishnu, some large and some small.

In one of the enchanting early monsoon days of 2017, I’d visited to this one of the most rare examples and oldest temples in Bagan, which is an only remaining Hindu shrine dedicated to Vishnu. Obviously for Hindu Indians, including merchants, slaves, artisans, skilled workers, including Brahmins as the employees of the king and elites. However, some native citizens of ancients Bagan also had worshipped there possibly. Assumed that it was built in the 11th century, during the reign of King Anawratha. Some believe it was built in the 10th century, during the reign of King Nyaung-u Sawrahan. As one of the oldest temples in Bagan, its style inspired as a prototype for the numerous structures that built up in coming years. Nat-hlaung kyaung literally means "Shrine confining the spirits" in Burmese language, reflecting the legend stated that the temple was built to detain all the deities (Nat) from other temples. However the real name seems to be Nat Hlyaung Kyaung, means “Shrine of reclining deity” evidently more righteous. It is because among the four facets of the central pillar inside the hall, the one which facing main entrance showed the statue of Vishnu reclining on the coils of the serpent Shesha. Other three facets also revealed the various forms identifying of Brahma, Vishnu and Shiva as one being: Trimurti. Once, outside the temple, there was surrounded by the statues of the 10 Avatars of Vishnu, including Gautama Buddha, but only seven can be seen today. The brick temple with a wide terrace was isolated and under repairing when I’d visited, damaged by recent earthquake. Hoping all the renovations completed now!
