Thatbyinnyu Temple with Shwegugyi Temple beyond it on the right as seen from Shwesandaw Pagoda.
Thatbyinnyu Temple was built circa 1150 and is Bagan’s tallest at 61 meters (200 feet). It was never fully completed or possibly even consecrated. Damage from the 1975 earthquake required restoration.
Shwegugyi Temple, built in 1131, is the oldest of the temples in the Bamar (the largest and culturally dominant ethnic group in Myanmar) architectural style.
