Wat Phra That Ha Duang is located close to Wat Phra That Duang Diao on highway 106 and is approached through an arch in gold and silver on the left. These two temples are among the last remaining from the Hariphunchai Kingdom suggesting that there must have been quite a large garrison here then. It’s known that Queen Chamathewi came here to pay tribute. It’s also clear that the area was abandoned for a very long time. Presumably after Lanna became a vassal state of Siam there was no longer the need for a garrison. It’s probably only in the last 100 years that some resettlement has taken place and the beautiful structures we see onsite today added on top of original bases built of laterite.
