Kyansittha Cave Temple, also known as Kyansittha Umin, is located at western Nyaung U. Although its name means “cave of Kyansittha”, archeological evidence shows that it may actually be built under the reign of King Anawrahta.
The cave temple serves as a lodging space for monks, with dark and long corridors decorated with countless frescoes. Some of these wall paintings illustrate Mongul invaders who took over Bagan after the year of 1287. Overall, the cave is around 9 meters high and 23.5 meters long.
