Vihara Nam Taem or the gilded Vihara north of the grand pagoda is regarded as a model of open Vihara built by the artist of Lampang School. It is a petty building with poles and beams as a main structure to shoulder the Mah Tang Mai roof structure. Roof accessory includes the ridged pole (Choh Fah), which was originally the fired earthen tile, and the ridge of a roof is decorated with the fired earthen Kranok plank functioning as Brali. In the middle of the ridge of a roof there is a ridge tile higher than the other in the form of lotus blossom with a sharply pointed top. It might represent Prasaat Phoeng in the story of Sumeru Mountain. On the rough walls of both sides of Vihara there are mural paintings depicting the story of Magha-manob or Maghamanava and Lady Samavadi. It is written with the technique of dust color. Some characters in the story are analogous to those in the Burmese art. It is assumed that it might have been created by the turn of 22nd Buddhist century (16th century A.D.). In addition, there are a few gilded designs on the pole and on some accessory, which are built in the related time of Vihara construction and also created during the course of times. At the back of Vihara is enshrined the Buddha image called “Phra Chao Saam Mn Thong”, which was, according to the chronicle, cast at the same time as Phra Chao Lan Thong.
