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.
