Wat Mahawan Wanaram, formerly known as Wat Mahawaram, is one of the historically significant temples of Lamphun, believed to have been built around the 12th Buddhist century. It is traditionally regarded as one of the four temples established during the reign of Queen Chamadevi, the ruler of the Haripunchai Kingdom. Over time, the temple experienced periods of prominence and decline. Like many religious sites in the region, it was eventually abandoned as a result of wars and political instability.
