Wiang Chao Ngo is an archaeological site characterized by a moat and earthen embankment surrounding the site, reflecting the settlement patterns of ancient communities in the northern river basin of Thailand. The physical features of the area still clearly show the earthen embankments and remnants of the moat, even though some parts have been landscaped for tourism and educational purposes. This area is located in Thung Yang Subdistrict, Lablae District, an area with overlapping historical and archaeological evidence from multiple eras.

Historically and archaeologically, areas with a "Wiang" (a type of moated city) in the Uttaradit river basin are often interpreted as communities with a long development period, possibly beginning in the late prehistoric era and continuing into the Dvaravati and Sukhothai cultures. However, precise dating of Wiang Chao Ngo requires further in-depth archaeological evidence, and currently, assessments are based more on the overall structural form and context of the area rather than definitive dating.

The name "Wiang Chao Ngo" originates from local beliefs and storytelling that connect the area to the folk tale "Sang Thong," viewing it as an area associated with legendary characters such as Chao Ngo or Phra Sang. This cultural interpretation enhances the value of tourism and the learning of Thai literature. Although not direct historical evidence, this belief plays a significant role in shaping the area's identity and making the archaeological site more widely known.

Currently, the area has been developed into a cultural tourism destination. The landscape has been improved for visitor access, including the restoration of the moat, the construction of walkways, and the creation of sculptures depicting characters from the Sang Thong story, such as Phra Sang and Nang Rojjana. This allows visitors to experience both the historical and folk literary dimensions simultaneously. Furthermore, its proximity to Wat Phra Borom That Thung Yang, the religious and cultural center of the area, makes this location an important link for historical, cultural, and community tourism in Lablae District.
