This is a semi-derelict temple and is therefore a bit different from the usual temples we visited. We were almost 'templed out' but went anyway. It was worth a stop, particularly if you are in the area, but you don't need much time there.
We cycled around the city one afternoon with our 2 children and found this city to be very enjoyable. You can cycle around the entire walled city in a couple of hours, stopping along the way to admire the mightly Mekong and sample some of the Chinese cuisine.
