The temple was practically in ruins until recently. It has been re-consecrated with a new wiharn and made a royal temple. There are actually two temples on two levels of the mountain-top. At the lower level is Wat Chom Chaeng, with a small ancient brick chedi and a relatively modern ubosot.
The ubosot is a beautiful example of the Chiang Saen style, with an intricately detailed gable. The platform of the ubosot affords a great view of Chiang Saen and the Mekhong River. Inside is a large Buddha image sitting under an artificial Bodhi tree.
You reach the big chedi of Wat Phrathat Chom Kitti on the upper level by climing a naga stairway up to the platform of the chedi, which also holds a rather make-shift wiharn. The chedi sits on a square base with standing Buddha images in niches on each of the four sides. Although a lot of the decorative elements have broken off, the Buddhas retain some rather interesting features.
At the base of the hill on which Wat Phrathat Chom Kitti sits there is a sacred well said to have curative powers. The well is a short way off the main road. Its watched over by a large contemporary Buddha image. Note that women are not supposed to go near the well.
