Following the catastrophic 7.7-magnitude earthquake on March 28, 2025, which struck central Myanmar, a large archaeological site has emerged in Tada-U Township with the ruins of an ancient royal structure belonging to the Konbaung Dynasty. The earthquake, which caused extensive damage and a heavy death toll, also induced geologic shifts that uncovered long-abandoned ruins near the ancient city of Inwa (formerly known as Ratnapura), about 10 kilometers from Mandalay.

The buildings, according to an official report by the Department of Archaeology and National Museum, are believed to be the remains of a royal water residence during the Konbaung era. Initial signs of the site had emerged as early as 2009, when locals chanced upon the remains of a mango-shaded staircase while brickmaking. The earthquake, however, recently uncovered deep fissures in the area, which unearthed additional architectural elements that had remained buried in the earth for centuries.

Test excavations began on April 6, 2025, by the Mandalay branch of the Department of Archaeology. Items exposed include a handrail of the eastern staircase, adjacent brick platforms, and measurement details such as a 10-foot-6-inch-long platform and an 18-inch riser step.


Though initial excitement gave rise to theories that the location may be the ancient “royal water pavilion” mentioned in palm-leaf manuscripts called “Pura-pike,” subsequent investigations point towards a less presumptuous interpretation. The manuscripts, allegedly authored by Minister Letwe Nawrahta in the time of King Hsinbyushin and the King of Sagaing, describe a royal water structure with five large staircases, teak buildings, and 18 to 20 halls that were shaded with mango trees.

Even with such descriptions, archaeologists today believe the recently discovered structure was most likely a wooden residence, measuring 200–250 feet by 200 feet, and was built utilizing traditional Burmese techniques. According to experts, it may have resembled monastic buildings like the Bahakara Monastery in Inwa or the Golden Palace Monastery of Mandalay, with mango-shaded staircases and wooden columns.

The site’s historical importance is also complemented by its ᴀssociation with royal rituals such as the Thingyan Water Festival and ceremonial hair-washing, which attest to its role in the spiritual and cultural life of the Konbaung court.

Conservation efforts are being undertaken to safeguard the site for public education and cultural heritage.
