Wat Phra That Haripunchai was rebuilt under the patronage of King Tilokaraja of the Lanna Kingdom, based in Chiang Mai. In 1443, the central stupa was enlarged and refined, its bell-shaped anda adorned with repoussé Buddha images hammered into bronze sheets. These serene figures, affixed directly to the stupa, are classic examples of early Lanna artistry, blending elegance with restrained spiritual symbolism.
