Wat Chedi Luang's massive chedi (pagoda) was built sometime between 1385 and 1402, during the reign of King Saen Muang Ma, 7th ruler of the Mengrai dynasty and is a distinctive feature of the Chiang Mai skyline. At its peak, the chedi measured 60 metres across at the square base and 80 metres tall and was once the home of the Emerald Buddha, Thailand's most sacred religious relic.
Damaged during an earthquake in 1545, the chedi’s height is reduced to nearly half of its original size yet it is still an impressive structure. In 1992, the Fine Arts Department finished restoration work around the chedi, bringing back the naga (water serpent) staircase on each of its faces and wonderful statues of elephants adorning the base. The actual work on the chedi itself, however, was never quite complete, leaving it in its present state.
