This pagoda is also one of the oldest in Shwebo and dates back to the Bagan Period. It derives its’ name from the venerable Thein (Sima) or Ordination Hall where monks are ordained into the Order. The inscriptions on the two bells in the pagoda were donated by King Badon mentions that the pagoda was built by King Narapati Sithu. Its unusual feature is that it is enclosed within three walls. The outer two walls are in ruins due to dereliction but the innermost stone wall is well preserved. A visit to these ancient pagodas would be worth the trouble.
