The Temple of Lady Ngoc and the Van Thuong Hai was built in the 19th century and is located in Thuong Chau Hamlet, Ngu Phung Commune, situated on a white sandy beach next to the seashore. The architectural complex of this heritage site is arranged within the same enclosure but serves two different worship functions.

When viewed from the front, the main temple is dedicated to Lady Ngoc (also known as Po Inư Nagar or Thien Ya Na Dien Ngoc Phi), a revered goddess honored by the Cham people as the Mother of the Land.

The main temple on the left side is dedicated to Ong Nam Hai (the Lord of the Southern Sea) and the benefactors who contributed to gathering people, establishing settlements, and developing fishing villages.

Every year, the Temple of Lady Ngoc and the Van Thuong Hai hosts two main religious festivals: the Spring Festival in the lunar month of January and the Autumn Festival in the lunar month of August.

Over the course of more than 200 years of existence, the Temple of Lady Ngoc and the Van Thuong Hai has undergone several repairs and renovations. With its unique and remarkable historical and cultural values, the temple has been recognized as a provincial-level historical and cultural relic by the People’s Committee of Binh Thuan Province, according to Decision No. 2958/QD-UBND dated November 16, 2007.
