Next to the well known temple of Wat Chedi Luang is a small interesting temple called Wat Pan Tao, which means "to increase 1,000 times." The temple was built around the same time as Wat Chedi Luang, in the late fourteenth century. It was one of four monastic temples serving the royal temple next door. The temple's most interesting feature is its wooden Viharn, a chapel for lay people to pray in. The teak building was moved to the temple grounds in 1875 by King Inthawichayanon. It was formerly a royal residence. Over the main entry door on the east end of the Viharn is a large gilded wood carving depicting a peacock flanked by several other animals, some of which are mythical. The peacock was the symbol of the kings of Chiang Mai; this carving has appeared on stamps and other materials celebrating Chiang Mai's 700^th anniversary. Within the Viharn are several interesting old artifacts, such as the Dhamma casket. The ancient wooden box holds Buddhist scriptures written on palm leaves. A few sample 'books' are usually on display above the casket. The caskets are finished in black lacquer decorated with gold leaf. Also on display is a tall pulpit-like stand, ornately carved and gilded. These structures, known as a Busabok, are not used by priests, but are usually used to house important Buddha images. The hall is also decorated with several tung prayer flags. Along one side is a platform for the monks to use during prayers, with all the priestly paraphernalia on display.
