The temple buildings seen today were built in the fifteenth century, and one of the reasons for the temple's popularity is the relatively pure state of all the temple buildings. Unlike most of the temples in Chiang Mai, Wat Phra That Lampang Luang hasn't been 'improved' to conform to modern Thai ideas about temples. The courtyard is still filled with sand, and the huge main wiharn (prayer hall) is still open on all sides.
