The Thành Hoàng Shrine of Mỹ Khê Village, also referred to as the communal house (đình) of Mỹ Khê in Tam Thanh Commune, was built around the year 1752, the same time as the construction of the Mỹ Khê Lady’s Tomb (Lăng Cô Mỹ Khê).

The shrine still preserves five imperial decrees (sắc phong) granted to the local guardian deity (Thành Hoàng Bổn Cảnh) during the reigns of Emperors Tự Đức, Đồng Khánh, and Khải Định. Each year, two major ceremonial offerings (tế lễ) are held at the shrine: the Spring Festival in the first lunar month, which prays for peace, favorable weather, and good harvests; and the Autumn Festival in the seventh lunar month, which is a thanksgiving ceremony to the deity.

On Phú Quý Island, the folk belief in worshiping the Thành Hoàng Bổn Cảnh is maintained by local communities in their village shrines. According to historical research, in 1839 under Emperor Minh Mạng, a royal decree mandated that each locality establish an altar for the Thành Hoàng Bổn Cảnh in their communal house. The title refers to the guardian deity (Thành Hoàng) protecting the community (Bổn Cảnh refers to the local place where the deity is venerated).

It is quite common that the Thành Hoàng Bổn Cảnh is not based on any historical or clearly documented human figure. Instead, the deity is viewed as a symbolic official appointed by the emperor to spiritually oversee a specific locality. In most shrines, the Thành Hoàng is not represented with a statue, but simply honored with a wooden plaque or altar inscribed with the character “Thần” (神), meaning “spirit” or “deity.”
