The Pyathadar is a very large, impressive brick temple that lies southeast of Old Bagan. The massive structure, also called Pyathatgyi, is one of the few remaining ‘double cave monasteries’. Most of these temples were built of wood and already disappeared.
The Pyathadar was built in the first half of the 13th century by King Kyaswa, a devout Buddhist. It is one of the last huge temples built in Bagan, as space became scarce in the Bagan Empire in the 13th century.
The late-day temple shows the progress of the architectural skills of Bagan master builders in the use of large vaulted rooms and wide corridors. The Pyathadar houses several large sitting and standing pictures of the Buddha in various positions. A project to restore the Pyathadar Temple was completed in 1998.
