Bupaya Pagoda is a notable pagoda located in Bagan (formerly Pagan), in Myanmar, at a bend on the right bank of the Ayeyarwady River. The small pagoda, which has a bulbous shaped dome, is widely believed to have been built by the third King of Pagan, Pyusawhti who ruled from 168 to 243 AD. It is one of the most notable shrines among the thousands of new or ruined Pagodas in Pagan, which is located about 90 miles (140 km) south of Mandalay.
The original pagoda was completely destroyed in the 1975 earthquake. As result of this earthquake, the bulbous pagoda broke into pieces and fell into the river. It was, however, fully reconstructed using modern materials, with lesser adherence to the original design. Subsequently it was built as a gilded superstructure.
The dating of this pagoda has several versions. According to the earliest claimed historical records, the Bupaya Pagoda claimed as the oldest, was built in the 3rd century by the third king of Pagan, Pyusawdi, who ruled from 168 to 243 AD. However, it is also reported that the pagoda was commissioned in the 2nd century by King Pyusawti. On the basis of similar pagodas and city walls built in Pagan, it has been conjectured that Bupaya Pagoda was built in the 9th century or even 11th century.
However, the old pagoda getting destroyed completely and falling into the Irrawaddy River during the 1975 earthquake, has indelibly scotched any arguments on the subject of its dating.
