“Paitings on Wall similar to Penang's”
Paintings on building wall are made in several spots in Betong downtown, locally called "street art". This street art looks similar to Penang's and Songkla's.
Tourists love to take pictures and following the gestures painted on the wall. Most of the paintings are narrating the lifestyle of local people now and years ago. They are inspired and painted by students and teachers of Silapakorn Universities, led by Archarn Amarith Choosuwan.
I may count about 11 spots of these kinds of paintings. You may find a map of these paintings from hotels or simply ask the local people.
