Yang Na Rangsi Temple, formerly known as “Wat Phaya Yang,” is an ancient temple of great historical significance in Lopburi. It is believed to have been established during the Lavo period, as evidenced by sandstone Buddha images in the Lopburi art style enshrined inside the ordination hall, reflecting the prosperity of Buddhism in ancient times. During the Ayutthaya and Rattanakosin periods, the temple underwent continuous restoration and was renamed “Wat Yang Sri Suthammararam” before officially becoming “Wat Yang Na Rangsri” as it is known today. The temple is located on the western bank of the Lopburi River, offering beautiful scenery and a cool, refreshing breeze throughout the day.

The most prominent highlight that has brought Yang Na Rangsi Temple widespread recognition is its historic wooden sermon hall, built in 1927. This wooden structure is a rare and well-preserved example of traditional central Thai rural temple architecture, which has become increasingly difficult to find today. Owing to its outstanding architectural and historical value, the sermon hall received the Architectural Conservation Award in 1993, making it a source of pride for both the local community and Lopburi Province.

Inside the historic wooden sermon hall, the building has been transformed into Thailand’s first folk boat museum. The museum houses a diverse collection of traditional boats that were once actively used in the river-based lifestyle, including dugout canoes carved from a single tree trunk, mad boats, paddled boats, and vessels used for trade and agriculture. The exhibits not only display the boats themselves but also explain traditional boat-building wisdom, the close relationship between people and waterways, and the vital role the Lopburi River played in the past.

The surrounding atmosphere of the temple is shaded and simple, characterized by large yang-na trees that provide ample shade and give the temple its name. The tranquility of the area makes it ideal for relaxation and for learning about local history. In addition, Wat Yang Na Rangsri is supported by young local guides—students from the community—who enthusiastically share knowledge about the boats, the temple’s history, and the traditional riverine way of life, leaving a lasting impression on visitors.

For families and cultural travelers, Yang Na Rangsi Temple is a unique destination that offers a different experience from typical temple visits in Lopburi. Visitors not only have the opportunity to make merit and pay respect to sacred objects, but also to gain insight into the roots of Thai river-based society through valuable traditional boats and wooden architecture. The temple thus serves as a harmonious link between faith, history, and traditional ways of life that continue to be preserved for future generations.
