Bueng Ngong, also referred to in some historical texts as “Bueng Nong Ngong,” is a large natural freshwater wetland covering an area of approximately 90 rai. It is located in Mueang Kao Subdistrict, Sao Hai District, Saraburi Province. This wetland is historically significant as it is believed to be the origin of the name “Saraburi Province,” which is still in use today.

Historical evidence suggests that during the founding of Saraburi in the Ayutthaya period, under the reign of King Maha Chakkraphat, the city was established near this large natural water source. The word “Sara” refers to the wetland itself, which served as a vital water reservoir for the community, while “Buri” means city. Combined, the name “Saraburi” clearly reflects the close relationship between the ancient settlement and its surrounding water resources.

The physical characteristics of Bueng Ngong are particularly distinctive. It is shaped like a semi-circular curve resembling a horseshoe, formed by a historical change in the course of the Pa Sak River. In geographical terms, this type of landform is known as an oxbow lake. The original name of the wetland was “Bueng Khong,” meaning a curved wetland, which later evolved into “Bueng Ngong” due to local pronunciation over time.

In the past, the area surrounding Bueng Ngong served as the administrative and settlement center of early Saraburi. The city center was later relocated to Phai Lom Subdistrict and subsequently to Pak Phriao Subdistrict, which constitutes the present-day downtown area of Saraburi. Despite these changes, the old city area around Bueng Ngong still preserves clear traces of its historical importance.

Today, Bueng Ngong is not only a water source for local residents of Sao Hai District, but also a recreational and historical attraction offering scenic views throughout the year. Along the edge of the wetland stands Wat Chanthaburi, an ancient temple renowned for its old ordination hall and valuable mural paintings.

A visit to Bueng Ngong is therefore akin to traveling back in time to the birthplace of Saraburi. Visitors can experience the serene riverside atmosphere of a traditional community, where simplicity, tranquility, and the historical essence of the Pa Sak River basin remain beautifully preserved.
