Wat Hang Dong is a typical example of traditional Lan Na temple architecture. The old viharn at this temple is a little more elaborate than its counterpart at nearby Wat Ton Kwen, but is essentially similar in shape, style and appearance. Also dark and intimate, with a low, sweeping, three-tiered roof, the viharn shelters a collection of Buddha images, at least two of which to the right and left of the main Buddha image are distinctively Lao in style and yet somehow strangely primitive. The old viharn at Wat Hang Dong has now been beautifully restored, and a new ubosot has also been added just a few metres to the northwest. This newer structure follows quite faithfully the traditional Lan Na design (the sum of some windows are perhaps over-elaborate and seem to show significant traces of Burmese influence), but overall the new ubosot at Wat Hang Dong both mirrors and complements the old viharn.
