In the way of these things, you mught also find this place referred to as Upalithein. The name refers to a monk, and the building dates from the mid 13th century. Actually it is not a temple as such but an ordination hall for monks. It was also used for monks to make confession. I must admit I thought confession was only a Christian idea.
When I visited, I was shown round by a wonderful old gentleman who was cleaning the place and spoke a degree of English.
Althuugh not a particularly large building, it is home to some wonderful wall paintings from the 17th and 18th centuries. Unfortunately, there was a some destruction caused by an earthquake in 1975, and the place now has a rather unsightly but obviously necessary metal framework inside (donated by UNESCO) to stop further collapse. The roof of the building, although rendered in stone, is meant to represent a Burmese wooden roof style.
Due to the delicacy of the frescoes, no photography is alloed inside the building.
An ordination hall along the Bagan-Nyaung U road. Although i never went in, it was claimed to contain beautiful paintings on the wall.
