Dong Hoa Hiep Commune
There are several ancient houses (private homes built by wealthy families in the mid- to late 19th century) throughout Dong Hoa Hiep, the most notable being Mr Kiet's Ancient House (1838) and Ba Duc Ancient House (1850), both of which have been restored, are open to the public, and have restaurants; others have been abandoned or fallen into disrepair. It's most efficient to visit on a tour since the more interesting houses are scattered, though it is possible to try to seek them out on your own as there are some signs on the road.
